EF10 NICs from the 8000 series onwards support TX offloads (checksumming,
 TSO) on VXLAN- and NVGRE-encapsulated packets.  This series adds driver
 support for these offloads.

Changes from v1:
 * Fix 'no TXQ of type' error handling in patch #1 (and clear up the
   misleading comment that inspired the wrong version)
 * Add comment in patch #5 explaining what the deal with TSOv3 is

Edward Cree (7):
  sfc: decouple TXQ type from label
  sfc: define inner/outer csum offload TXQ types
  sfc: create inner-csum queues on EF10 if supported
  sfc: select inner-csum-offload TX queues for skbs that need it
  sfc: de-indirect TSO handling
  sfc: implement encapsulated TSO on EF10
  sfc: advertise encapsulated offloads on EF10
