Now that I've looked at the differences between different controller
revisions, it appears that the switch in byte ordering for the multicast
hash bitmap was made between the RTL8169 family (PCI) and RTL8168 family
(PCI Express). The recent fix applied to some members of the latter
family.
One difference I noted between the vendor driver and the in-tree driver
is in the ordering of register writes. It probably doesn't make a
difference, but perhaps you could try changing:
RTL_W32(MAR0 + 0, mc_filter[0]);
RTL_W32(MAR0 + 4, mc_filter[1]);
RTL_W32(RxConfig, tmp);
to:
RTL_W32(RxConfig, tmp);
RTL_W32(MAR0 + 0, mc_filter[0]);
RTL_W32(MAR0 + 4, mc_filter[1]);
in rtl_set_rx_mode().
