This doesn't seem to be in mr. Romieu's patch above: should it go in on top of that? I ask because with the forementioned patch the newer integrated NICs seem to be recognised correctly and preliminary testing shows no disconnect issues, but performance is nothing to write home about (one of these days I'll get into a rant about samba speed vs. ftp speed, but this is not the time nor place). > Reference: > http://www.spinics.net/lists/netdev/msg40384.html > Bruce Cole LF - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
