net: Prepare for IPsec GRO
This patch prepares the generic codepath for IPsec GRO.
We introduce a new GRO_CONSUMED notifyer to reflect that
IPsec can return asynchronous. On IPsec GRO we grab the
packet and reinject it back to layer 2 after IPsec
processing. We also use one xfrm_gro bit on the sk_buff
that will be set from IPsec to notify about GRO. If this
bit is set, we call napi_gro_receive for the backlog device
instead of __netif_receive_skb.
