Hi Yevgeny! Actually on further testing it seems that things are still not perfect with my old firmware at least.
If I do "ifconfig eth6 mtu 1450" (where eth6 is a mlx4_en interface) then I am no longer able to get traffic through the interface; if I have a ping running it stops immediately. It seems any mtu change triggers this (increasing the mtu above the default has the same effect, and restoring the mtu to the default doesn't fix it). Haven't tried to debug further. - R. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
