[net-next 00/11][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

The following series contains updates to e1000e and ixgbe. The one
patch for e1000e makes function tables const, thanks to Stephen
Hemminger for reporting this.  The remaining patches are for ixgbe,
and the contain the following:

 - minor cleanups
 - add support for 82599 device and ethtool -E support
 - removal of a PHY which is not used in production silicon

The following are changes since commit 56fd49e399ce1d82200fad5b8924d4e35a587809:
  bna: Driver Version changed to 3.0.2.2
and are available in the git repository at
  git://github.com/Jkirsher/net-next.git

Emil Tantilov (8):
  ixgbe: prevent link checks while resetting
  ixgbe: clear the data field in ixgbe_read_i2c_byte_generic
  ixgbe: remove return code for functions that always return 0
  ixgbe: add support for new 82599 device
  ixgbe: send MFLCN to ethtool
  ixgbe: do not disable flow control in ixgbe_check_mac_link
  ixgbe: remove instances of ixgbe_phy_aq for 82598 and 82599
  ixgbe: allow eeprom writes via ethtool

[net-next 02/11] ixgbe: prevent link checks while resetting

[Jeff Kirsher]

From: Emil Tantilov <emil.s.tantilov@intel.com>

It some situations the driver sets __IXGBE_RESETTING and then
__IXGBE_DOWN flags. It is possible a link check may sneak in
between.

This patch adds check for both flags.
The idea is to reduce register reads while the PHY is resetting.

[net-next 05/11] ixgbe: fix driver version initialization in firmware

[Jeff Kirsher]

From: Jacob Keller <jacob.e.keller@intel.com>

This patch fixes an issue with storing the driver version for the
firmware. If the os does not support the particular firmware
management tools, the firmware requires a driver version to be written
as 0xFFFFFFFF rather than the actual driver version.

[net-next 09/11] ixgbe: get pauseparam autoneg

[Jeff Kirsher]

From: Mika Lansirinne <mika.lansirinne@stonesoft.com>

There is a problem in the ixgbe driver with the reporting of the flow
control parameters. The autoneg parameter is shown to be of if
*either* it really is off, or current modes for both tx and rx are off.

The problem is seen when the parameters are read or set when the link
is down. In this case, the driver sees that tx and rx are currently off
and therefore autoneg parameter is incorrectly reported to be off too.
Also, the ethtool binary can not set the autoneg off since it sees that
it already is. When a link later comes up, the autonegotiation is
carried out normally and the driver later on reports the autoneg
parameter to be on (as it is) and then it can also be changed with
ethtool.

The patch is made against v3.0 kernel, but the problem seems to be there
since v2.6.30-rc1.

Reviewer comments: What we are trying to do is to disable flow control
while the cable is disconnected. Since ixgbe defaults to full flow
control, we call ethtool -A autoneg off rx off tx off while the cable
is disconnected. This doesn't work, because the driver sets
hw->fc.current_mode = ixgbe_fc_none if the cable is unplugged.
ixgbe_get_pauseparam() then reports to ethtool that nothing needs to be
done. The code fixes this, but it might have some unknown consequences.

Currently there is only 1 small change that needs to be made to patch 11
of the series, based on Ben's comments.

I will wait a bit longer before fixing up patch 11, to ensure that there
are no other changes needed.

[net-next 00/11][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to igb, igbvf, ixgbe, i40e and i40evf.

Emil provides a ixgbe patch to fix the detection of SFP+ capable interfaces
by identifying 82599 based NICs with no PHY type set as SFP capable which
allows the driver to detect the SFP module when the interface is brought
up.

Jacob provides eight patches to cleanup the ixgbe driver to resolve various
checkpatch.pl warnings/errors as well as minor coding style issues.

Stephen Hemminger and I provide simple cleanups of void functions which
had useless return statements at the end of the function which are not
needed.

The following are changes since commit 86b5d251d5ac4dda51a022b34cb29b4ce65a8cd5:

[net-next 00/11][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to vxlan, net, ixgbe, ixgbevf, and i40e.

Joseph provides a single patch against vxlan which removes the burden
from the NIC drivers to check if the vxlan driver is enabled in the
kernel and also makes available the vxlan headrooms to the drivers.

Jacob provides majority of the patches, with patches against net, ixgbe
and ixgbevf.  His net patch adds might_sleep() call to napi_disable so
that every use of napi_disable during atomic context will be visible.
Then Jacob provides a patch to fix qv_lock_napi call in
ixgbe_napi_disable_all.  The other ixgbe patches cleanup
ixgbe_check_minimum_link function to correctly show that there are some
minor loss of encoding, even though we don't calculate it and remove
unnecessary duplication of PCIe bandwidth display.  Lastly, Jacob
provides 4 patches against ixgbevf to add ixgbevf_rx_skb in line with
how ixgbe handles the variations on how packets can be received, adds
support in order to track how many packets were cleaned during busy poll
as part of the extended statistics.

Wei Yongjun provides a fix for i40e to return -ENOMEN in the memory
allocation error handling case instead of returning 0, as done
elsewhere in this function.

The following are changes since commit cdfb97bc010d9e9d994eb68f2cbac3a8ada26104:

[net-next 00/11][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

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

Dan Carpenter provides a patch for igbvf to fix a bug found by a static
checker.  If the new MTU is very large, then "new_mtu + ETH_HLEN +
ETH_FCS_LEN" can wrap and the check on the next line can underflow.

Wei Yongjun provides 2 patches, the first against igbvf adds a missing
iounmap() before the return from igbvf_probe().  The second against
i40e, removes the include <linux/version.h> because it is not needed.

Carolyn provides a patch for igb to fix a call to set the master/slave
mode for all m88 generation 2 PHY's and removes the call for I210
devices which do not need it.

Stefan Assmann provides a patch for igb to fix an issue which was broke
by:
   commit fa44f2f185f7f9da19d331929bb1b56c1ccd1d93
   Author: Greg Rose <gregory.v.rose@intel.com>
   Date:   Thu Jan 17 01:03:06 2013 -0800
   igb: Enable SR-IOV configuration via PCI sysfs interface
which breaks the reloading of igb when VFs are assigned to a guest, in
several ways.

Jacob provides a patch for ixgbe and ixgbevf.  First, against ixgbe,
cleans up ixgbe_enumerate_functions to reduce code complexity.  The
second, against ixgbevf, adds support for ethtool's get_coalesce and
set_coalesce command for the ixgbevf driver.

Yijing Wang provides a patch for ixgbe to use pcie_capability_read_word()
to simplify the code.

Emil provides a ixgbe patch to fix an issue where the logic used to
detect changes in rx-usecs was incorrect and was masked by the call to
ixgbe_update_rsc().

Don provides 2 patches for ixgbevf.  First creates a new function to set
PSRTYPE.  The second bumps the ixgbevf driver version.

The following are changes since commit b45bd46decd947eaa3497699d450e0851d247534:

1.8.3.1

[net-next 00/11][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to ixgbe only.

My previous pull request had a mix of ixgbe and igb patches, and
while Akeem works on the changes requested on the igb patches, I
going ahead and re-submitting the originally submitted ixgbe patches
with several other ixgbe patches.

Alex provides a performance improvement with the enabling the use of
build_skb for instances where jumbo frames are disabled.  In addition,
Alex provides a fix where we were incorrectly checking the entire frag_off
field when we only wanted the fragment offset.  Lastly, he cleans up
the check for PAGE_SIZE, since the default configuration allocates 32K
for all buffers.

Emil provides a change to the calculation of eerd so that it is consistent
between the read and write functions by using | instead of +.

Jacob adds support for displaying PCIe Gen3 link speed, which was
previously missing from the ixgbe driver.  He also provides a patch
to clean up ixgbe_get_bus_info_generic to call some conversion
functions, which are used also in another patch provided by Jacob.
Jacob modifies the driver to enable certain devices (which have an
internal switch) to read from the physical slot rather than reading
data from the internal switch.  Lastly, Jacob adds a function which
enables the ixgbe driver to walk up the PCI bus for the device and
query the PCI config space for the bus width at each point.


Don provides a couple of fixes (which are more appropriate for net-next),
one of which resolves an issue where ixgbe was only turning on the laser
when the adapter was up which caused issues for those who wanted to
access the MNG firmware while the port was in a down state.  The other
fix is for WoL when currently linked at 1G.  Lastly Don bumps the driver
version keep the in-kernel driver up to date with the current functionality.

The following are changes since commit 6c6779856a294649dbb468ef46e893e80b0d72ad:
  Revert "netprio_cgroup: make local table static"
and are available in the git repository at:
  git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next master

Alexander Duyck (3):
  ixgbe: Support using build_skb in the case that jumbo frames are
    disabled
  ixgbe: Mask off check of frag_off as we only want fragment offset
  ixgbe: Drop check for PAGE_SIZE from ixgbe_xmit_frame_ring

Don Skidmore (3):
  ixgbe: fix MNG FW support when adapter not up
  ixgbe: Fix 1G link WoL
  ixgbe: bump version number

Emil Tantilov (1):
  ixgbe: don't do arithmetic operations on bitmasks
