  This patchset fixes the Rx checksum flags in net/tap
driver. The first two patches are the effective fixes.

The last 2 patches introduce a new checksum API to
verify a L4 checksum and its unt test, in order to
simplify the net/tap code, or any other code that has
the same needs.

v2:

* clarify why RTE_PTYPE_L3_IPV4_EXT_UNKNOWN cannot happen in
  tap_verify_csum() (patch 1)
* align style of rte_ipv6_udptcp_cksum_verify() to
  rte_ipv4_udptcp_cksum_verify() (patch 3)
* clarify comment above rte_ipv4_udptcp_cksum_verify() and
  rte_ipv6_udptcp_cksum_verify() (patch 3)


Olivier Matz (4):
  net/tap: fix Rx cksum flags on IP options packets
  net/tap: fix Rx cksum flags on TCP packets
  net: introduce functions to verify L4 checksums
  test/cksum: new test for L3/L4 checksum API
