This patch fixes a VT mode check to make sure VLAN filters are disabled when
in promisc mode and VT is not enabled.
The problem with the previous check was that:
E1000_MRQC_ENABLE_VMDQ is defined as 0x00000003
but when not in VT mode:
mrqc |= E1000_MRQC_ENABLE_RSS_4Q (0x00000002)
So the above check will trigger regardless if VT mode is being used or not.

If the ready bit in the transmit buffer descriptor (TxBD[R])
is previously detected as not set during a prior frame transmission,
then the ENET_TDAR[TDAR] bit is cleared at a later time, even if
additional TxBDs were added to the ring and the ENET_TDAR[TDAR]
bit is set. This results in frames not being transmitted until
there is a 0-to-1 transition on ENET_TDAR[TDAR].
Workarounds:
code can use the transmit frame interrupt flag (ENET_EIR[TXF])
as a method to detect whether the ENET has completed transmission
and the ENET_TDAR[TDAR] has been cleared. If ENET_TDAR[TDAR] is
detected as cleared when packets are queued and waiting for transmit,
then a write to the TDAR bit will restart TxBD processing.
This case main happen when loading is light. A ethernet package may
not send out utile next package put into tx queue.
How to test:
while [ true ]
do
ping <IP> -s 10000 -w 4
ping <IP> -s 6000 -w 2
ping <IP> -s 4000 -w 2

atl1c uses netdev_alloc_skb to refill its rx dma ring, but that call makes no
guarantees about the suitability of the memory for use in DMA. As a result
we've gotten reports of atl1c drivers occasionally hanging and needing to be
reset:
https://bugzilla.kernel.org/show_bug.cgi?id=54021
Fix this by modifying the call to use the internal version __netdev_alloc_skb,
where you can set the gfp_mask explicitly to include GFP_DMA.
Tested by two reporters in the above bug, who have the hardware to validate it.

usbnet doesn't support yet SG, so drivers should not advertise SG or TSO
capabilities, as they allow TCP stack to build large TSO packets that
need to be linearized and might use order-5 pages.
This adds an extra copy overhead and possible allocation failures.
Current code ignore skb_linearize() return code so crashes are even
possible.
Best is to not pretend SG/TSO is supported, and add this again when/if
usbnet really supports SG for devices who could get a performance gain.

The work queue is initialised in rtl_open (when the interface goes up),
but canceled in rtl_remove_one (when the PCI device gets removed). If
the network interface is not brought up, then the work queue struct is
not initialised. When the device is removed, the attempt to cancel the
uninitialised work queue causes a lockdep warning.
This patch fixes the issue by moving cancel_work_sync to rtl_close (to
match rtl_open). (Note that rtl_close is also called via
unregister_netdev in rtl_remove_one.)

During tear down (e.g. mwifiex_sdio_remove during system suspend),
mwifiex left IRQs enabled for a significant period of time when it was
unable to handle them correctly. This caused interrupt storms and
interfered with the bluetooth interface on the same SDIO card.
Solve this by disabling interrupts at the point when they can no longer
be handled correctly, which is at the start of mwifiex_remove_card().
For cleanliness, we now enable interrupts in the mwifiex_add_card() path,
to be symmetrical with the disabling of interrupts. We also couple the
registration of the sdio IRQ handler with the actual enable/disable of
interrupts at the hardware level.
I also removed a write to this register in mwifiex_init_sdio which seemed
pointless and won't cause any ill effects now that we only register
the SDIO IRQ handler when we are ready to accept interrupts.

it is possible for open followed by close to occur before the

The esd_usb2_read_bulk_callback() function is parsing the data that comes from
the USB CAN adapter. One datum is used as an index to access the dev->nets[]
array. This patch adds the missing bounds checking.

Pull networking fixes from David Miller:
"A couple interesting SKB fragment handling fixes, plus the usual small
bits here and there:
1) Fix 64-bit divide build failure on 32-bit platforms in mlx5, from
Tim Gardner.
2) Get rid of a stupid reimplementation on "%*phC" in our sysfs MAC
address printing helper.
3) Fix NETIF_F_SG capability advertisement in hyperv driver, if the
device can't do checksumming offloads then it shouldn't say it can
do SG either. From Haiyang Zhang.
4) bgmac needs to depend on PHYLIB, from Hauke Mehrtens.
5) Don't leak DMA mappings on mapping failures, from Neil Horman.
6) We need to reset the transport header of SKBs in ipv4 before we
attempt to perform early socket demux, just like ipv6 does. From
Eric Dumazet.
7) Add missing locking on vxlan device removal, from Stephen
Hemminger.
8) xen-netfront has to make two passes over an SKB to prepare it for
transfer. One pass calculates the number of slots needed, the
second massages the SKB and fills the slots. Unfortunately, the
first pass doesn't calculate the number of slots properly so we
can end up trying to build a MAX_SKB_FRAGS + 1 SKB which doesn't
work out so well. Fix from Jan Beulich with help and discussion
with several others.
9) Fix a similar problem in tun and macvtap, which have to split up
scatter-gather elements at PAGE_SIZE boundaries. Don't do
zerocopy if it would result in a > MAX_SKB_FRAGS skb. Fixes from
Jason Wang.
10) On receive, once we've decoded the VLAN state completely, clear
skb->vlan_tci. Otherwise demuxed tunnels underneath can trigger
the VLAN code again, corrupting the packet. Fix from Eric
Dumazet"

Pull x86 fixes from Peter Anvin:
"Trying again to get the fixes queue, including the fixed IDT alignment
patch.
The UEFI patch is by far the biggest issue at hand: it is currently
causing quite a few machines to boot. Which is sad, because the only
reason they would is because their BIOSes touch memory that has
already been freed. The other major issue is that we finally have
tracked down the root cause of a significant number of machines
failing to suspend/resume"
