FWIW, that existing code doesn't actually work in any case. I've been running with an MTU of 7200 on one such NIC for some time, and L0s and L1 are definitely enabled, even though the driver says it's turning them off. I'll try your patch shortly, probably tomorrow. (Now I only have to worry about the *other* bug that's been bruited about on this list -- the one where the card locks up if its peer shuts down. It's worrying because one of my 82574Ls has a peer that's regularly suspended... I guess I'll try and see if I can reproduce that lockup!) -- NULL && (void) ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
