Given all the code does operate on struct ifnet, the last step in this longer series of changes now is to rename struct net_device to struct ifnet (that is what it was defined to in the LinuxKPi code). While mlx4 and OFED are "shared" code the decision was made years ago to not write it based on the netdevice KPI but the native ifnet KPI for most of it. This commit simply spells this out and with that frees "struct netdevice" to be re-done on LinuxKPI to become a more native/mixed implementation over time as needed by, e.g., wireless drivers.
