This controller seems to support MSI-X with 4 messages.
Unfortunately previous PCIe controllers from RealTek were notorious
for MSI issues so it's hard to know this revision really works with
MSI-X. I guess it was added to support RSS(receive-side scaling of
MS NDIS 6.0).
As sephe said if the controller configuration is the same as 8168C
family, the attached patch would make re(4) work as expected.
