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
