Perhaps ether_addr_equal for some API naming semi-consistency.

$ grep "\bint.*is_.*ether_addr" include/linux/etherdevice.h
static inline int is_zero_ether_addr(const u8 *addr)
static inline int is_multicast_ether_addr(const u8 *addr)
static inline int is_local_ether_addr(const u8 *addr)
static inline int is_broadcast_ether_addr(const u8 *addr)
static inline int is_unicast_ether_addr(const u8 *addr)
static inline int is_valid_ether_addr(const u8 *addr)

Perhaps all of these should be bool too
