net: Clarification of CHECKSUM_UNNECESSARY
This patch: - Clarifies the specific requirements of devices returning CHECKSUM_UNNECESSARY (comments in skbuff.h). - Adds csum_level field to skbuff. This is used to express how many checksums are covered by CHECKSUM_UNNECESSARY (stores n - 1). This replaces the overloading of skb->encapsulation, that field is is now only used to indicate inner headers are valid. - Change __skb_checksum_validate_needed to "consume" each checksum as indicated by csum_level as layers of the the packet are parsed. - Remove skb_pop_rcv_encapsulation, no longer needed in the new csum_level model.
