Anyway.

I am ok with removing NET_IP_ALIGN because it is already defined in 
skbuff.h to 2.
But increasing NET_SKB_PAD to 64 caused that Microblaze extends skb 
buffers for some bytes.
I measured it by iperf and netperf and I see regression around 1-2Mbit/s 
that's why I would like to ask you to revert this patch or keep at least 
NET_SKB_PAD part.

Thanks,
Michal
