The ethernet port on my ASUS A88X Pro mainboard stopped working
several times a day, with messages like these in dmesg:
AMD-Vi: Event logged [IO_PAGE_FAULT device=05:00.0 domain=0x001e address=0x0000000000003000 flags=0x0050]
Searching the web for these messages led me to similar reports about
different hardware supported by r8169, and eventually to commits
3ced8c955e74d319f3e3997f7169c79d524dfd06 ('r8169: enforce RX_MULTI_EN
for the 8168f.') and eb2dc35d99028b698cdedba4f5522bc43e576bd2 ('r8169:
RxConfig hack for the 8168evl'). So I tried this change, and it fixes
the problem for me.

For RTL8411, RTL8111G, RTL8402, RTL8105, and RTL8106, disable the feature
of entering the L2/L3 link state of the PCIe. When the nic starts the process
of entering the L2/L3 link state and the PCI reset occurs before the work
is finished, the work would be queued and continue after the next the PCI
reset occurs. This causes the device stays in L2/L3 link state, and the system
couldn't find the device.

net: get rid of SET_ETHTOOL_OPS
Dave Miller mentioned he'd like to see SET_ETHTOOL_OPS gone.
This does that.
Mostly done via coccinelle script:
@@
struct ethtool_ops *ops;
struct net_device *dev;
@@
- SET_ETHTOOL_OPS(dev, ops);
+ dev->ethtool_ops = ops;
Compile tested only, but I'd seriously wonder if this broke anything.

Replace the bh safe variant with the hard irq safe variant.
We need a hard irq safe variant to deal with netpoll transmitting
packets from hard irq context, and we need it in most if not all of
the places using the bh safe variant.
Except on 32bit uni-processor the code is exactly the same so don't
bother with a bh variant, just have a hard irq safe variant that
everyone can use.

None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>. Most are just a

Windows driver will enable ALDPS function, but linux driver and firmware
do not have any configuration related to ALDPS function for 8168g.
So restart system to linux and remove the NIC cable, LAN enter ALDPS,
then LAN RX will be disabled.
This issue can be easily reproduced on dual boot windows and linux
system with RTL_GIGA_MAC_VER_40 chip.
Realtek said, ALDPS function can be disabled by configuring to PHY,
switch to page 0x0A43, reg0x10 bit2=0.

For some reason, my PCIe RTL8111E onboard NIC on a GA-Z68X-UD3H-B3
motherboard reads as FFs when reading from MMIO with a block size
larger than 7. Therefore change to reading blocks of four bytes.
Ben Hutchings noted that the buffer is large enough to hold all
registers, so now all registers are read.

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.)

8168evl offloaded checksums are wrong since commit
e5195c1f31f399289347e043d6abf3ffa80f0005 ("r8169: fix 8168evl frame padding.")
pads small packets to 60 bytes (without ethernet checksum). Typical symptoms
appear as UDP checksums which are wrong by the count of added bytes.
It isn't worth compensating. Let the driver checksum.
Due to the skb length changes, TSO code is moved before the Tx descriptor gets
written.

This was introduced in commit 6dccd16 "r8169: merge with version
6.001.00 of Realtek's r8169 driver". I did not find the version
6.001.00 online, but in 6.002.00 or any later r8169 from Realtek
this hunk is no longer present.
Also commit 05af214 "r8169: fix Ethernet Hangup for RTL8110SC
rev d" claims to have fixed this issue otherwise.
The magic compare mask of 0xfffe000 is dubious as it masks
parts of the Reserved part, and parts of the VLAN tag. But this
does not make much sense as the VLAN tag parts are perfectly
valid there. In matter of fact this seems to be triggered with
any VLAN tagged packet as RxVlanTag bit is matched. I would
suspect 0xfffe0000 was intended to test reserved part only.
Finally, this hunk is evil as it can cause more packets to be
handled than what was NAPI quota causing net/core/dev.c:
net_rx_action(): WARN_ON_ONCE(work > weight) to trigger, and
mess up the NAPI state causing device to hang.
As result, any system using VLANs and having high receive
traffic (so that NAPI poll budget limits rtl_rx) would result
in device hang.
