c593642c8b treewide: Use sizeof_field() macro
Replace all the occurrences of FIELD_SIZEOF() with sizeof_field() except
at places where these are defined. Later patches will remove the unused
definition of FIELD_SIZEOF().

This patch is generated using following script:

EXCLUDE_FILES="include/linux/stddef.h|include/linux/kernel.h"

git grep -l -e "\bFIELD_SIZEOF\b" | while read file;
do

	if [[ "$file" =~ $EXCLUDE_FILES ]]; then
		continue
	fi
	sed -i  -e 's/\bFIELD_SIZEOF\b/sizeof_field/g' $file;
done

0fc75219fe r8169: fix rtl_hw_jumbo_disable for RTL8168evl
In referenced fix we removed the RTL8168e-specific jumbo config for
RTL8168evl in rtl_hw_jumbo_enable(). We have to do the same in
rtl_hw_jumbo_disable().

398fd408cc r8169: fix resume on cable plug-in
It was reported [0] that network doesn't wake up on cable plug-in with
certain chip versions. Reason is that on these chip versions the PHY
doesn't detect cable plug-in when being in power-down mode. So prevent
the PHY from powering down if WoL is enabled.

Alan reported [0] that network is broken since the referenced commit

a0783cd0c8 r8169: disable TSO on a single version of RTL8168c to fix performance
During performance testing, I found that one of my r8169 NICs suffered
a major performance loss, a 8168c model.

Running netperf's TCP_STREAM test didn't return the expected
throughput of > 900 Mb/s, but rather only about 22 Mb/s.  Strange
enough, running the TCP_MAERTS and UDP_STREAM tests all returned with
throughput > 900 Mb/s, as did TCP_STREAM with the other r8169 NICs I can
test (either one of 8169s, 8168e, 8168f).

Bisecting turned up commit 93681cd7d9,
"r8169: enable HW csum and TSO" as the culprit.

I added my 8168c version, RTL_GIGA_MAC_VER_22, to the code
special-casing the 8168evl as per the patch below.  This fixed the
performance problem for me.

718af5bc97 r8169: improve conditional firmware loading for RTL8168d
Using constant MII_EXPANSION is misleading here because register 0x06

parameter is read by writing the parameter id to register 0x05 on page
0x0005, followed by reading the parameter value from register 0x06.

2df49d3654 r8169: remove fiddling with the PCIe max read request size
The attempt to improve performance by changing the PCIe max read request
size was added in the vendor driver more than 10 years back and copied
to r8169 driver. In the vendor driver this has been removed long ago.
Obviously it had no effect, also in my tests I didn't see any
difference. Typically the max payload size is less than 512 bytes
anyway, and the PCI core takes care that the maximum supported value
is set. So let's remove fiddling with PCIe max read request size from
r8169 too.

dc161162e4 r8169: don't set bit RxVlan on RTL8125
RTL8125 uses a different register for VLAN offloading config,
therefore don't set bit RxVlan.

b3a42e3a78 r8169: add support for EEE on RTL8125
This adds EEE support for RTL8125 based on the vendor driver.
Supported is EEE for 100Mbps and 1Gbps. Realtek recommended to not yet
enable EEE for 2.5Gbps due to potential compatibility issues. Also
ethtool doesn't support yet controlling EEE for 2.5Gbps and 5Gbps.

f1bce4ad2f r8169: add support for RTL8125
This adds support for 2.5Gbps chip RTL8125, it's partially based on the
r8125 vendor driver. Tested with a Delock 89531 PCIe card against a
Netgear GS110MX Multi-Gig switch. Firmware isn't strictly needed,
but on some systems there may be compatibility issues w/o firmware.
Firmware has been submitted to linux-firmware.
