3c574 and 3c589 endianness fixes (.24?)
Browse files Browse the repository at this point in the history
Both store MAC address in CIS; there's no decoder for that
type (0x88) so the drivers work with raw data.  It is
byteswapped, so ntohs() works for little-endian, but for
big-endian it's wrong.  ntohs(le16_to_cpu()) does the
right thing on both (and always expands to swab16()).
