      ixgbevf: Add support for generic Tx checksums · cb2b3edb
      Alexander Duyck authored
      
      
      This patch adds support for generic Tx checksums to the ixgbevf driver.  It
      turns out this is actually pretty easy after going over the datasheet as we
      were doing a number of steps we didn't need to.
      
      In order to perform a Tx checksum for an L4 header we need to fill in the
      following fields in the Tx descriptor:
        MACLEN (maximum of 127), retrieved from:
      		skb_network_offset()
        IPLEN  (maximum of 511), retrieved from:
      		skb_checksum_start_offset() - skb_network_offset()
        TUCMD.L4T indicates offset and if checksum or crc32c, based on:
      		skb->csum_offset
      
      The added advantage to doing this is that we can support inner checksum
      offloads for tunnels and MPLS while still being able to transparently
      insert VLAN tags.
      
      I also took the opportunity to clean-up many of the feature flag
      configuration bits to make them a bit more consistent between drivers.  In
      the case of the VF drivers this meant adding support for SCTP CRCs, and
      inner checksum offloads for MPLS and various tunnel types.
