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.
