There is no caller of function iavf_debug_d() in tree since
commit 75051ce4c5d8 ("iavf: Fix up debug print macro"),
so it can be removed.

This patch fixed issue in VM which shows no link when hypervisor is
restored from low-power state. The driver is responsible for re-enabling
any features of the device that had been disabled during suspend calls,
such as IRQs and bus mastering.

From: Kai-Heng Feng <kai.heng.feng@canonical.com>
After hot plugging an 1Gbps Ethernet cable with 1Gbps link partner, the
MII_BMSR may report 10Mbps, renders the network rather slow.
The issue has much lower fail rate after commit 59653e6497d1 ("e1000e:
Make watchdog use delayed work"), which essentially introduces some
delay before running the watchdog task.
But there's still a chance that the hot plugging event and the queued
watchdog task gets run at the same time, then the original issue can be
observed once again.
So let's use mod_delayed_work() to add a deterministic 1 second delay
before running watchdog task, after an interrupt.

In the function fm10k_xmit_frame_ring, we recently switched to using
the skb_frag_size accessor instead of directly using the size member of
the skb fragment.
This made the for loop slightly harder to read because it created a very
long line that is difficult to split up. Avoid this by using a local
variable in the for loop, so that we do not have to break the line on an
open parenthesis.

Allow the VF to override the "permanent" MAC address set by the host.
This allows bonding to work in the case where the administrator has set
the VF MAC.
Note that the VF must still be set to Trusted on the host if this change
is to be accepted by the PF driver.

From: "Mauro S. M. Rodrigues" <maurosr@linux.vnet.ibm.com>
There are several uses of hw_dbg in the code, producing no output. This
patch implements it using dev_debug.
Initially the intention was to implement it using netdev_dbg, analogously
to what is done in ixgbe for instance. That approach was avoided due to
some early usages of hw_dbg, like i40e_pf_reset, before the VSI structure
initialization causing NULL pointer dereference during the driver probe if
the debug messages were turned on as soon as the module is probed.
v2:
- Use dev_dbg instead of pr_debug, and take advantage of dev_name
instead of crafting pretty much the same device name locally as suggested
by Jakub Kicinski.

Since commit
'5098850c9b9b ("i40e/i40evf: i40e_register.h updates")'
it is no longer possible to trigger an EMP Reset from debugfs, but it's
possible to request it either way, to end up with a bad reset request:
echo empr > /sys/kernel/debug/i40e/0002\:01\:00.1/command
i40e 0002:01:00.1: debugfs: forcing EMPR
i40e 0002:01:00.1: bad reset request 0x00010000
So let's remove this piece of code and show the available valid commands
as it is when any invalid command is issued.

From: Firo Yang <firo.yang@suse.com>
In Xen environment, if Xen-swiotlb is enabled, ixgbe driver
could possibly allocate a page, DMA memory buffer, for the first
fragment which is not suitable for Xen-swiotlb to do DMA operations.
Xen-swiotlb have to internally allocate another page for doing DMA
operations. This mechanism requires syncing the data from the internal
page to the page which ixgbe sends to upper network stack. However,
since commit f3213d932173 ("ixgbe: Update driver to make use of DMA
attributes in Rx path"), the unmap operation is performed with
DMA_ATTR_SKIP_CPU_SYNC. As a result, the sync is not performed.
Since the sync isn't performed, the upper network stack could receive
a incomplete network packet. By incomplete, it means the linear data
on the first fragment(between skb->head and skb->end) is invalid. So
we have to copy the data from the internal xen-swiotlb page to the page
which ixgbe sends to upper network stack through the sync operation.
More details from Alexander Duyck:
Specifically since we are mapping the frame with
DMA_ATTR_SKIP_CPU_SYNC we have to unmap with that as well. As a result
a sync is not performed on an unmap and must be done manually as we
skipped it for the first frag. As such we need to always sync before
possibly performing a page unmap operation.
