NAME
compare_ether_addr_64bits - Compare two Ethernet addressesSYNOPSIS
- 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 lqmemcmp(addr1, addr2, ETH_ALEN)rq 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.
