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

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

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