compare_ether_addr_64bits — Compare two Ethernet addresses
unsigned compare_ether_addr_64bits ( | const u8 addr1[6+2], |
const u8 addr2[6+2]); |
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.
