You're right. I've missed to update revision entry. :-) I guess MSI-X requires a documentation from RealTek as it may have to map interrupt source to MSI-X vectors. It may also need to map PBA to MSI-X work on 8168D. Would you show me dmesg output of re(4)? Thanks for the patch and testing! -- Regards, Pyun YongHyeon _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[EMAIL PROTECTED]"
