All: We recently upgraded some test systems to the ixgbe 3.7.14 driver from the ixgbe 3.3.9 driver. Sometime between 3.3.9 and 3.7.14 this line got added to ixgbe_write_mc_addr_list in ixgbe_main.c:
hw->mac.ops.update_mc_addr_list(hw, NULL, 0, ixgbe_addr_list_itr, true); Unfortunately, this seems to have the effect of zeroing out the multicast address list the NIC is listening to before re-adding all the multicast addresses. This has the net effect of dropping packets from existing multicast streams when adding additional multicast sockets. I looked and this change also exists in the latest ixgbe 3.12.6 driver. Is there a reason why this clear was added? I looked through the mailing list and didn't find any references. I don't want to just comment out and recompile to resolve our particular situation if we run the risk of hitting another bug. On a side note, I was trying to find a changelog for ixgbe_main.c . It looks like there is no source repo on Sourceforge. Should I be looking somewhere else?
