nfp: devlink port split support for 1x100G CXP NIC This commit makes it possible to use devlink to split the 100G CXP Netronome into two 40G interfaces. Currently when you ask for 2 interfaces, the math in src/nfp_devlink.c:nfp_devlink_port_split calculates that you want 5 lanes per port because for some reason eth_port.port_lanes=10 (shouldn't this be 12 for CXP?). What we really want when asking for 2 breakout interfaces is 4 lanes per port. This commit makes that happen by calculating based on 8 lanes if 10 are present.
