- Enable interrupts only at the end of epic_attach() when all the
other initializations succeeded. - Initialize the TX and RX rings in epic_attach() rather than in epic_init() where we're not supposed to fail. Similarly, free the TX and RX rings in epic_detach() rather than in epic_stop(). - Change epic_init() to be a void function now that it can't fail. Also change its parameter to a void * so that we have a correct prototype for if_init. - Now that epic_init() has a correct prototype, don't cast the function pointer when initializing if_init. - Fix nearby style bugs.
