bonding + igb TX queue warnings

bonding + igb TX queue warnings

[Phil Oester]

Running 2.6.36.3 here, and brought up a bond on 2 igb interfaces.
Syslog now getting flooded with this:

kernel: bond0 selects TX queue 16, but real number of TX queues is 16

Any way to change which queue bond0 is selecting or otherwise fix
this?

Hello,

I apologize for the delay in responding.  This looks like a bonding problem where the queue count isn't starting from zero as expected.  This part has 16 queues, but the highest queue selection would be 15, not 16.

Thanks,

Carolyn
