Re: [E1000-devel] Bonding + ixgbe breaks with jumbo frames if the MTU is not set on bond0 before adding slaves

2012-06-29 Thread Ko, Stephen S
Hi Nathan, Thanks for the report. We are trying to reproduce this issue in our lab. Could you please send us: - dmesg - modinfo bonding | head Just to narrow down the issue, have you tried this on all other interfaces besides ixgbe? (e.g. igb, e1000, or e1000e)? We will keep you informed

[E1000-devel] Bonding + ixgbe breaks with jumbo frames if the MTU is not set on bond0 before adding slaves

2012-06-29 Thread Nathan March
Hi All, I think I've found a bug in the ixgbe driver when using bonding + jumbo frames. Adding slaves to the bond device and setting mtu 9000 after enslaving, results in one of the slaves dropping traffic. The strange thing is putting bond0 into promiscuous mode (by running tcpdump) will solve

[E1000-devel] e1000e: only 10M full-duplex after suspend / reloading module works

Hi, I'm running a Debian kernel and at least since 3.2 I've got a problem with my 82579LM (in a Thinkpad T420). If I plug in a network cable after waking my laptop from suspend I get 10M full-duplex instead of the 100M or 1000M the other side is capable of. If I remove and re-insert the module I g
