The patch doesn't include any fixes from FreeBSD driver. The root cause of the multicast issue of the rge driver was that it didn't identify the mac version correctly, it think rtl8168c as a *pci* variant, not pcie variant. As the multicast filter formats are different between pci and pcie variants of rtl8168/8169 family, rge with rtl1868c could not accept multicast packets. In addition, the pcie variants have a bug that it will hang in transmitting. The rge driver includes a workaround for the tx hang, but it was not enabled for rtl8168c because of the incorrect identification. That is why I thought the new patch might resolve the hang issue. -masa _______________________________________________ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
