Hi Andrew, could you please share the patch as I'm dying with this problem. What makes it worse is that on a busy router the DOWN/UP of the interfaces causes the ixgbe card to lose all network access until the box is rebooted. I can reproduce it easily on a variety of hosts from both HP and Dell. Therefore a patch that would not cause the card to reset would help a lot. -- Igor On Thu, May 19, 2011 at 8:58 PM, Andrew Boyer <aboyer@averesystems.com> wro= te: > I have a patch that will fix this. =C2=A0Please give me a little while to= clean it up, and I will send it out on the list. > > -Andrew > > On May 19, 2011, at 2:58 AM, Igor Anishchuk wrote: > >> Hi All, >> >> I've been using Intel E10G42AFDA 10Gbit/s AF DA Dual Port adapters >> with direct attach cables and there is one thing keeps bothering me. >> I've been searching the Internet for any information with no luck.
