nfp: bpf: require ETH table
Upcoming changes will require all netdevs supporting TC offloads to have a full struct nfp_port. Require those for BPF offload. The operation without management FW reporting information about Ethernet ports is something we only support for very old and very basic NIC firmwares anyway.
