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.

The last 2 patches may be postponed to 20.08 if required.

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
