[ Upstream commit e89df5c4322c1bf495f62d74745895b5fd2a4393 ]
There is a race condition exist during termination. The path is
alx_stop and then alx_remove. An alx_schedule_link_check could be called
before alx_stop by interrupt handler and invoke alx_link_check later.
Alx_stop frees the napis, and alx_remove cancels any pending works.
If any of the work is scheduled before termination and invoked before
alx_remove, a null-ptr-deref occurs because both expect alx->napis[i].
This patch fix the race condition by moving cancel_work_sync functions
before alx_free_napis inside alx_stop. Because interrupt handler can call
alx_schedule_link_check again, alx_free_irq is moved before
cancel_work_sync calls too.

The bad access is in neigh_hh_output(), at skb->data - 16 (HH_DATA_MOD).
atl1c driver provided skb with no headroom, so 14 bytes (ethernet
header) got pulled, but then 16 are copied.
Reserve NET_SKB_PAD bytes headroom, like netdev_alloc_skb().
Compile tested only; I lack hardware.

[ Upstream commit 881d0327db37ad917a367c77aff1afa1ee41e0a9 ]
Note: This is a verified backported patch for stable 4.4 kernel, and it
could also be applied to 4.3/4.2/4.1/3.18/3.16
There is a problem with alx devices, that the network link will be
lost in 1-5 minutes after the device is up.
>From debugging without datasheet, we found the error always
happen when the DMA RX address is set to 0x....fc0, which is very
likely to be a HW/silicon problem.
This patch will apply rx skb with 64 bytes longer space, and if the
allocated skb has a 0x...fc0 address, it will use skb_resever(skb, 64)
to advance the address, so that the RX overflow can be avoided.

[ Upstream commit f43bfaeddc79effbf3d0fcb53ca477cca66f3db8 ]
atl2 includes NETIF_F_SG in hw_features even though it has no support
for non-linear skbs. This bug was originally harmless since the
driver does not claim to implement checksum offload and that used to
be a requirement for SG.
Now that SG and checksum offload are independent features, if you
explicitly enable SG *and* use one of the rare protocols that can use
SG without checkusm offload, this potentially leaks sensitive
information (before you notice that it just isn't working). Therefore
this obscure bug has been designated CVE-2016-2117.

atl1c driver is doing order-4 allocation with GFP_ATOMIC
priority. That often breaks networking after resume. Switch to
GFP_KERNEL. Still not ideal, but should be significantly better.
atl1c_setup_ring_resources() is called from .open() function, and
already uses GFP_KERNEL, so this change is safe.

This patch adds the PCI device ID (0xe0a1) and alx_pci_tbl entry for the
Killer E2400 Ethernet controller, modeled after the Killer E2200
controller support (0xe091) already present in the alx driver.
This patch was originally authored by Ben Pope, but it got held up by
issues in the commit message, so I'm resubmitting it on his behalf.
I've extensively used a kernel with this patch on a System76 serw9
laptop and am quite confident it works well (at least on the hardware I
have available for testing).
Note that as a favor to System76, Ubuntu has been carrying this as a
sauce patch in their 4.2 based Wily kernel, which presumably has given
it real-world testing on other E2400 equipped hardware (I don't know of
any Ubuntu kernel bugs filed about it):

This howto made sense in the 1990s when users had to manually configure
ISA cards with jumpers or vendor utilities, but with the implementation
of PCI it became increasingly less and less relevant, to the point where
it has been well over a decade since I last updated it. And there is
no value in anyone else taking over updating it either.
However the references to it continue to spread as boiler plate text
from one Kconfig file into the next. We are not doing end users any
favours by pointing them at this old document, so lets kill it with
fire, once and for all, to hopefully stop any further spread.
No code is changed in this commit, just Kconfig help text.

Commit d75b1ade567f ("net: less interrupt masking in NAPI") uncovered
wrong alx_poll() behavior.
A NAPI poll() handler is supposed to return exactly the budget when/if
napi_complete() has not been called.
It is also supposed to return number of frames that were received, so
that netdev_budget can have a meaning.
Also, in case of TX pressure, we still have to dequeue received
packets : alx_clean_rx_irq() has to be called even if
alx_clean_tx_irq(alx) returns false, otherwise device is half duplex.

1. For the 64 bits dma mask use dma_set_mask_and_coherent instead of
dma_set_mask and dma_set_coherent_mask.
2. For the 32 bits dma mask dma_set_coherent_mask is only called if
dma_set_mask fails, which is unusual. Assuming this as a bug, fixes
it by replacing calls to dma_set_mask and dma_set_coherent_mask by a

As Ben Hutchings pointed out for the stats in alx, some
hardware-specific stats aren't matched to the right net_device_stats

number of RX/TX packets.
Minor whitespace fixes to match the style in alx.
