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 ...

The controller requires two queues for tx and two queues for rx. Controller fetch buffer from free queue and then push to used queue. Diver should prepare free queue and free buffer from used queue.
