Subject: [PATCH net v2 0/2] nfp: flower: a few small conntrack offload fixes

This small series addresses two bugs in the nfp conntrack offloading
code.

The first patch is a check to prevent offloading for a case which is
currently not supported by the nfp.

The second patch fixes up parsing of layer4 mangling code so it can be
correctly offloaded. Since the masks are an inverse mask and we are
shifting it so it can be packed together with the destination we
effectively need to 'clear' the lower bits of the mask by setting it to
0xFFFF.

Changes since v1:
- Added inline comment to the second patch
- Expanded the commit message to better explain the mask setting in the
  second patch.

  nfp: flower: add hardware offload check for post ct entry
  nfp: flower: fix hardware offload for the transfer layer port
