With QUIC getting more attention these days, it is worth
implementing UDP direct segmentation, the same we did for TCP.

Drivers will need to advertize NETIF_F_GSO_UDP_L4 so that
GSO stack does not do the (more expensive) segmentation.

Note the two first patches are stable candidates, after
tests confirm they do not add regressions.

v2: addressed Jakub feedback :
   1) Added a prep patch for octeontx2-af
   2) calls tso_start() earlier in otx2_sq_append_tso()

Eric Dumazet (6):
  octeontx2-af: change (struct qmem)->entry_sz from u8 to u16
  net: tso: double TSO_HEADER_SIZE value
  net: tso: shrink struct tso_t
  net: tso: constify tso_count_descs() and friends
  net: tso: cache transport header length
  net: tso: add UDP segmentation support

Series applied, thanks Eric.
