rS297389: Improve HW checksums support in VNIC
Summary
  • Do not mark CSUM_IP_CHECKED and CSUM_IP_VALID on IPv6 packets. IPv6 does not have checksums by definition.
  • Set SCTP packets csum_flags CSUM_SCTP_VALID instead of CSUM_DATA_VALID and skip csum_data
  • Set csum_data simply as 0xffff without byteswap
