ETHER_ADDR_EQUAL_64B(9) Network device support ETHER_ADDR_EQUAL_64B(9)

NAME

ether_addr_equal_64bits - Compare two Ethernet addresses

SYNOPSIS

bool ether_addr_equal_64bits(const u8 addr1, const u8 addr2);

ARGUMENTS

const u8 addr1

Pointer to an array of 8 bytes

const u8 addr2

Pointer to an other array of 8 bytes

DESCRIPTION

Compare two Ethernet addresses, returns true if equal, false otherwise.

The function doesn't need any conditional branches and possibly uses word memory accesses on CPU allowing cheap unaligned memory reads. arrays = { byte1, byte2, byte3, byte4, byte5, byte6, pad1, pad2 }

Please note that alignment of addr1 & addr2 are only guaranteed to be 16 bits.
