a patch for jumbo frame and others
I don't have a trouble denied some packets temporarily but a trouble dropped
many packets with jumbo frames. I use 12-current with a similar patch attached
this comment, and the patch does not make everything correct but makes
better condition.
I have three devices, 82574L, I217-V, I218-V. I don't have any trouble for
I21[78] regardless with or without the patch when mtu is 1500.
With 9k jumbo, without the patch, scp speed is very slow and
dev.em.0.rx_overruns increases.
On 82574L, dev.em.0.rx_overruns increases without the patch and
dev.em.0.mac_stats.recv_no_buff increases with the patch.
Above 6k jumbo, scp speed is almost 10kB/s without the patch
and the speed is about 10MB/s with the patch.
