nfp: bpf: relax prog rejection through max_pkt_offset
NFP is refusing to offload programs whenever the MTU is set to a value
larger than the max packet bytes that fits in NFP Cluster Target Memory
(CTM). However, a eBPF program doesn't always need to access the whole
packet data.
Verifier has always calculated maximum direct packet access (DPA) offset,
and kept it in max_pkt_offset inside prog auxiliar information. This patch
relax prog rejection based on max_pkt_offset.
