[net-next 00/12][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to e100 and e1000e.

The e100 patch from Andy simply updates the netif_printk() to use
%*ph to dump small buffers.

The changes to e1000e include a fix from Dean Nelson to resolve a
issue where a pci_clear_master() was accidentally dropped during a
conflict resolution. Wei Young provides 2 patches, one removes an
assignment of the default ring size because it was a duplicate. The
second changes the packet split receive structure to use
PS_PAGE_BUFFERS macro for the length so that problems won't occur
when the length is changed.

The remaining patches for e1000e are from Bruce Allan, where he
provides a number of fixes and updates for I218.  In addition, a
fix for 82583 which can disappear off the PCIe bus, to resolve this,
disable ASPM L1.  Bruce also provides a fix to a previous commit
(commit e60b22c5b7 e1000e: fix accessing to suspended device) so that
devices are only taken out of runtime power management for those
ethtool operations that must access device registers.

The following are changes since commit dcfe8048de66c3468060c8a2ec2c04ae3725d002:
  bonding: remove bond_resend_igmp_join_requests read_unlock leftover

[net-next 02/12] e1000e: restore call to pci_clear_master()

[Jeff Kirsher]

From: Dean Nelson <dnelson@redhat.com>

In attempting to resolve a minor merge conflict, commit e5f2ef7ab4690d2e8faa
(Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net) accidentally
dropped a call to pci_clear_master() that was intended to remain in place.

Commit 4e0855dff094b0d56d6b (e1000e: fix pci-device enable-counter balance)
replaced a call to pci_disable_device() by one to pci_clear_master(). And then
commit 66148babe728f3e00e13 (e1000e: fix runtime power management transitions)
deleted a number of lines starting two lines following that call.

This patch restores the call to pci_clear_master() in __e1000_shutdown().

v2: added summary lines (enclosed in parens) following commit IDs

[net-next 03/12] e1000e: Remove duplicate assignment of default rx/tx ring size

[Jeff Kirsher]

From: Wei Yang <weiyang@linux.vnet.ibm.com>

tx_ring/rx_ring size is assigned in function e1000_alloc_queues(), which is
called by e1000_sw_init() in the early stage of e1000_probe().

This patch just remove the duplicate assignment of this default ring size
value.

[Jeff Kirsher]

From: Wei Yang <weiyang@linux.vnet.ibm.com>

In structure e1000_rx_desc_packet_split, the size of wb.upper.length is
defined by a digit. This may introduce some problem when the length is
changed.

This patch use the macro PS_PAGE_BUFFERS for the definition. And move the
definition to hw.h.

The 82583 can disappear off the PCIe bus.  This device is a modified 82574
which had the same problem which was fixed by disabling ASPM L1; disabling
it on 82583 fixes the issue on this device.

[net-next 06/12] e1000e: iAMT connections drop on driver unload when jumbo frames enabled

[Jeff Kirsher]

From: Bruce Allan <bruce.w.allan@intel.com>

The jumbo frame configuration in the MAC/PHY should be reverted on 82579
and newer parts when the interface is brought down (not just when the MTU
is changed back to standard frame size) otherwise iAMT connections (e.g.
SoL, IDE-R) will be dropped and cannot be re-acquired until the MTU is
changed again.

[net-next 08/12] e1000e: Tx hang on I218 when linked at 100Half and slow response at 10Mbps

[Jeff Kirsher]

From: Bruce Allan <bruce.w.allan@intel.com>

Tx hang is an unintended consequence of another workaround that is in the
EEPROM for an issue with the firmware at 10Mbps when K1 (a power mode of
the MAC-PHY interconnect) is enabled.  The issue is resolved by setting
appropriate Tx re-transmission timeouts in the PHY and associated K1 entry
times in the MAC to allow enough transmissions to occur without triggering
a Tx hang.  A similar change is needed when linked at 10Mbps to improve
latency.

[net-next 09/12] e1000e: ethtool unnecessarily takes device out of RPM suspend

[Jeff Kirsher]

From: Bruce Allan <bruce.w.allan@intel.com>

A previous patch (commit e60b22c5b7 e1000e: fix accessing to suspended
device) added .begin and .complete ethtool driver callbacks so that the
device was resumed from Runtime Power Management (RPM) suspend state for
all ethtool operations.  This is overkill for operations which do not need
to access any registers in the device.  This patch makes it so that the
device is taken out of RPM suspend only for those ethtool operations that
must access device registers.

[net-next 10/12] e1000e: enable support for new device IDs

[Jeff Kirsher]

From: Bruce Allan <bruce.w.allan@intel.com>

The device IDs 0x15a0 and 0x15a1 are new SKUs that contain the same MAC as
I217 and same PHY as I218.

The device IDs 0x15a2 and 0x15a3 are the same as existing I218 SKUs.

[net-next 11/12] e1000e: do not resume device from RPM suspend to read PHY status registers

[Jeff Kirsher]

From: Bruce Allan <bruce.w.allan@intel.com>

When the device is runtime suspended (e.g. when there is no link), do not
wake it from D3 to read the PHY status; just set the values to typical
power-on defaults as is done when runtime PM is not enabled and there is no
link.

[net-next 12/12] e1000e: fix I217/I218 PHY initialization flow

[Jeff Kirsher]

From: Bruce Allan <bruce.w.allan@intel.com>

The initialization of the PHY on I217/I218, while similar to 82579, must
also check to see if the MAC and PHY are in the same mode (PCIe vs. SMBus)
otherwise the PHY will be inaccessible by the MAC.

It looks like you pulled my net tree instead of my net-next tree.
Fortunately, I did not have anything applied to my net tree that had not
already been sent out.

Disregard, it was me misreading my git log in my net tree after updating
it against your latest tree.

When will your kernel.org net-next be updated?  I ask because I have a
series for ixgbe I am putting together and wanted to make sure it is
against the latest net-next.

Are you asking when I will next merge 'net' into 'net-next'?  If so,
I'll likely do it some time tomorrow.

I am not worried about that.  I just cloned your net-next tree and did
not see your pull of my net-next tree which had the e100 and e1000e
patches.  I am working on creating another series against net-next and
the tip on kernel.org is:

commit 9d4a0314642918cbda9ed4012df51e8df608fce6
Author: Hannes Frederic Sowa <hannes@stressinduktion.org>

    ipv4, ipv6: send igmpv3/mld packets with TC_PRIO_CONTROL

which is several days old.  So I was not sure if I just make my series
against my net-next tip.

Looks fine, pulled, thanks Jeff.

[net-next 00/12][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to i40e, igb, ixgbe and ixgbevf.

Shannon provides a couple of i40e patches, first restricts the ethtool
diag test messages by using netif_info() macro to when the hardware
bit is enabled in the message level netdev message mask.  Second
provides a fix for when there is an out-of-range descriptor request.

Kamil provides a fix for i40e by updating the loopback enum types and
add information about the current loopback mode to data returned from
get_link_info().

Jesse provides a fix for i40e define name that was being mis-used.
I40E_ITR_NONE was being used as an ITRN register index by accident
because it was easily associated with the i40e Rx ITR and friends
defines, when it should be associated with the DYN_CTL register sets.

Jacob provides an update for ixgbevf Kconfig description since the VF
driver supports more than just the 82599 device.

Don and Alex provide a cleanup patch for ixgbe to make it where head,
tail, next to clean and next to use are all reset in a single function
for both Tx and Rx path.  Before, the code for this was spread out over
several areas which made it difficult to track what the values were for
each of the values.

Carolyn provides two igb patches to add a media switching feature for
i354 PHY's and new Media Auto Sense for 82580 devices only.

Aaron Sierra provides a fix for igb to resolve an issue with the 64-bit
PCI addresses being truncated because the return values of
pci_resource_start() and pci_resouce_end() were being cast to unsigned
long.

Guenter Roeck provides two igb patches, first simplifies the code by
attaching the hwmon sysfs attributes to hwmon device instead of the

[net-next 00/12][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to e1000e, igb and ixgbe.

Bruce Allan provide 2 minor cleanups for e1000e to resolve whitespace
issues and build warnings about unused parameters.

Carolyn provides a couple of fixes for igb, one being a fix for a
possible panic when the interface is down and receive traffic
arrives.  The second fix resolves an issue on newer parts which have
multiple checksum fields and set_ethtool was only checking to update
the first checksum of the NVM image.

Akeem provides majority of the changes in this patch set.  Akeem
provides a fix for e1000e on an issue reported from the community to
resolve the issue of unlocking swflag_mutex for 82574 and 82583
devices even if the hardware semaphore was successfully acquired.
The other patches from Akeem are against igb, where he adds support
SFP module discovery, LED blink mechanism for devices using cathodes,
LED support for i210/i211 parts and cleanup of a i2c function which
was not being used.

Matthew provides an update for igb to support a more accurate check
for a PTP RX hang.

Amir provides a patch for ixgbe to set the software prio_tc values at
initialization to the hardware setting to remove the need to reset the
device at the first time we call ixgbe_dcbnl_ieee_setets.

The following are changes since commit 1e18583adccfc122b5d6415cfe4bf1826c370f4e:
  ThunderLAN: remove is_eisa flag
and are available in the git repository at:
  git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next master

Akeem G. Abodunrin (6):
  e1000e: Release mutex lock only if it has been initially acquired
  igb: Changed LEDs blink mechanism to include designs using cathode
  igb: Support for SFP modules discovery
  igb: SerDes flow control setting
  igb: Implementation of i210/i211 LED support
  igb: Removed unused i2c function

Amir Hanania (1):
  IXGBE: Set the SW prio_tc values at initialization to the HW setting.

Bruce Allan (2):
  e1000e: cleanup whitespace
  e1000e: prevent warning from -Wunused-parameter

Carolyn Wyborny (2):
  igb: Fix set_ethtool function to call update nvm for entire image
  igb: Fix possible panic caused by Rx traffic arrival while interface
    is down

Matthew Vick (1):
  igb: Add update to last_rx_timestamp in Rx rings

[net-next 00/12][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to e1000e, ixgbe and ixgbevf.

Majority of the changes are against e1000e (from Bruce Allan).
Bruce adds additional error handling on PHY register access, as
well as improve slow performance on 82579 when connected to a
10Mbit hub.  In addition, fixes LED blink logic for cathode
LED design.  Most notable is added EEE support which is enabled
by default and the added support for LTR on I217/I218.

The ixgbe and ixgbevf from Greg Rose changes the VM so that if a user
does not assign a MAC address, the MAC address is set to all zeros
instead of a random MAC address.  This ensures that we always know when
we have a random address and udev won't get upset about it.

The following are changes since commit 8b49a4c75965ed157e21450d23dcadd6b27c1aa3:
  bnx2x: fix compilation without CONFIG_BNX2X_SRIOV
and are available in the git repository at:
  git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next master

Bruce Allan (10):
  e1000e: additional error handling on PHY register accesses
  e1000e: slow performance between two 82579 connected via 10Mbit hub
  e1000e: fix LED blink logic for designs with LEDs driven by cathode
  e1000e: long access timeouts when I217/I218 MAC and PHY are out of
    sync
  e1000e: EEE capability advertisement not set/disabled as required
  e1000e: enable EEE by default
  e1000e: add support for LTR on I217/I218
  e1000e: cleanup unused defines
  e1000e: increase driver version number
  e1000e: fix scheduling while atomic bugs

I had to apply the following patch to fix the build on non-x86
architectures.

--------------------
e1000e: Need to include vmalloc.h

Otherwise (on sparc64):

drivers/net/ethernet/intel/e1000e/ethtool.c:657:3: error: implicit declaration of function 'vmalloc' [-Werror=implicit-function-declaration]
