COMPARE_ETHER_ADDR_6(9) 				      Network device support					   COMPARE_ETHER_ADDR_6(9)

NAME
       compare_ether_addr_64bits - Compare two Ethernet addresses

SYNOPSIS
       unsigned compare_ether_addr_64bits(const u8 addr1[6+2], const u8 addr2[6+2]);

ARGUMENTS
       addr1[6+2]
	   Pointer to an array of 8 bytes

       addr2[6+2]
	   Pointer to an other array of 8 bytes

DESCRIPTION
       Compare two ethernet addresses, returns 0 if equal. Same result than "memcmp(addr1, addr2, ETH_ALEN)" but without conditional branches, and
       possibly long word memory accesses on CPU allowing cheap unaligned memory reads. arrays = { byte1, byte2, byte3, byte4, byte6, byte7, pad1,
       pad2}

       Please note that alignment of addr1 & addr2 is only guaranted to be 16 bits.
