Interesting that you swapped napi_get_frags/napi_gro_frags for napi_alloc_skb/napi_gro_receive. I was under the impression that napi_get_frags/napi_gro_frags was the "correct" way to do things the other drivers that I was looking at use those methods. Does this make a big performance difference?

Also, need to fix tabs vs. spaces. Linux kernel coding standard is to use tabs.
