Hi!
First patch drops unnecessary version.h includes. Second one
drops support for pre-release versions of FW ABI. Removing
FW ABI 0.0 from supported set is particularly good since 0
could just be uninitialized memory. Last but not least I drop
unnecessary padding of frames on RX which makes us count bytes
incorrectly for the VF2VF traffic.

nfp: remove linux/version.h includes
nfp: drop support for old firmware ABIs
nfp: don't pad frames on receive
