interface. Make MII drivers forget about 'struct ifnet'. Later plan is to provide an administrative downcall from ifnet layer into drivers, to inform them about administrative status change. If someone thinks that processing MII events for an administratively down interface is a big problem, then drivers would turn MII processing off. The following MII drivers do evil things, like strcmp() on driver name, so they still need knowledge of ifnet and thus include if_var.h. They all need to be fixed: sys/dev/mii/brgphy.c sys/dev/mii/e1000phy.c sys/dev/mii/ip1000phy.c sys/dev/mii/jmphy.c sys/dev/mii/nsphy.c sys/dev/mii/rgephy.c sys/dev/mii/truephy.c Sponsored by: Netflix Sponsored by: Nginx, Inc.
