47ea032533 drivers/net: get rid of unnecessary initializations in .get_drvinfo()
Many drivers initialize uselessly n_priv_flags, n_stats, testinfo_len,
eedump_len & regdump_len fields in their .get_drvinfo() ethtool op.
It's not necessary as these fields is filled in ethtool_get_drvinfo().

v2: removed unused variable
v3: removed another unused variable

adc9048c60 net: hisilicon: fixes a bug when using ethtool -S
this patch fixes a bug in hns driver. when we want to get statistic info
by using ethtool -S, it shows us there are 3 wrong counters info. because
the strings related to the registers are wrong. it needs to modify the
strings which give us wrong info.

0fa28877b2 net: HNS: fix MDIO dependencies
The newly introduced HNS_MDIO Kconfig symbol selects 'MDIO', but
that is the wrong symbol as the code used by this driver is
provided by PHYLIB rather than the MDIO driver. Also, there is
no need to make this driver user selectable, because it is already
selected by all drivers that need it.

This changes the Kconfig file to select the correct library, and
to make the option silent.

dfdd7230c5 net: hns: fix 32-bit build warning
The recently added hns driver causes a build warning in ARM
allmodconfig builds:

138b15ed87 drivers/net: remove all references to obsolete Ethernet-HOWTO
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.

48b63776c8 net: hip04: Make tx coalesce timer actually work
The code sets the expiry value of the timer to a relative value and
starts it with hrtimer_start_expires. That's fine, but that only works
once. The timer is started in relative mode, so the expiry value gets
overwritten with the absolut expiry time (now + expiry).

So once the timer expired, a new call to hrtimer_start_expires results
in an immidiately expired timer, because the expiry value is
already in the past.

Use the proper mechanisms to (re)start the timer in the intended way.

a41ea46a9a net: hisilicon: new hip04 ethernet driver
Support Hisilicon hip04 ethernet driver, including 100M / 1000M controller.
The controller has no tx done interrupt, reclaim xmitted buffer in the poll.

v13: Fix the problem of alignment parameters for function and checkpatch warming.

v12: According Alex's suggestion, modify the changelog and add MODULE_DEVICE_TABLE
     for hip04 ethernet.

v11: Add ethtool support for tx coalecse getting and setting, the xmit_more
     is not supported for this patch, but I think it could work for hip04,
     will support it later after some tests for performance better.

     Here are some performance test results by ping and iperf(add tx_coalesce_frames/users),
     it looks that the performance and latency is more better by tx_coalesce_frames/usecs.

     - Before:
     $ ping 192.168.1.1 ...
     === 192.168.1.1 ping statistics ===
     24 packets transmitted, 24 received, 0% packet loss, time 22999ms
     rtt min/avg/max/mdev = 0.180/0.202/0.403/0.043 ms

     $ iperf -c 192.168.1.1 ...
     [ ID] Interval       Transfer     Bandwidth
     [  3]  0.0- 1.0 sec   115 MBytes   945 Mbits/sec

     - After:
     $ ping 192.168.1.1 ...
     === 192.168.1.1 ping statistics ===
     24 packets transmitted, 24 received, 0% packet loss, time 22999ms
     rtt min/avg/max/mdev = 0.178/0.190/0.380/0.041 ms

     $ iperf -c 192.168.1.1 ...
     [ ID] Interval       Transfer     Bandwidth
     [  3]  0.0- 1.0 sec   115 MBytes   965 Mbits/sec

v10: According David Miller and Arnd Bergmann's suggestion, add some modification
     for v9 version
     - drop the workqueue
     - batch cleanup based on tx_coalesce_frames/usecs for better throughput
     - use a reasonable default tx timeout (200us, could be shorted
       based on measurements) with a range timer
     - fix napi poll function return value
     - use a lockless queue for cleanup
