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.
