Implement functionality that enables drivers to expose to XDP code checksum
information that consists of:

- Checksum status - 2 non-exlusive flags:
  - XDP_CHECKSUM_VERIFIED indicating HW has validated the checksum
    (corresponding to CHECKSUM_UNNECESSARY in sk_buff)
  - XDP_CHECKSUM_COMPLETE signifies the validity of the second argument
    (corresponding to CHECKSUM_COMPLETE in sk_buff)
- Checksum, calculated over the entire packet, valid if the second flag is
  set

Only one stupid thing from me: when a line starts from '-' in the commit
message, some editors/viewers paint it red thinking it's a diff already
:z (same for '+')
Not something important, you just may want to prefer "neutral" '*', up
to you :D
