Merge branch 'nfp-fixes-for-v5-19'

Simon Horman says:

====================
nfp: fixes for v5.19

this short series includes two fixes for the NFP driver.

1. Restructure GRE+VLAN flower offload to address a miss match
   between the NIC firmware and driver implementation which
   prevented these features from working in combination.

2. Prevent unnecessary warnings regarding rate limiting support.-
   It is expected that this feature to not _always_ be present
   but this was not taken into account when the code to check
   for this feature was added.
