gro: Open-code frags copy in skb_gro_receive gcc does a poor job at generating code for the memcpy of the frags array in skb_gro_receive, which is the primary purpose of that function when merging frags. In particular, it can't utilise the alignment information of the source and destination. This patch open-codes the copy so we process words instead of bytes.
