Source: linux-2.6
Version: 2.6.32-31
Severity: wishlist
Tags: patch
Hi,
The igb driver up to 2.6.34 uses an incorrect check to detect the presence
of a management card sharing the network interface.
This can lead to a loss of network connectivity for the host and/or the
management card eventually.
The fix from upstream applies cleanly to 2.6.32 and is attached to this
bug report for convenience.
Thanks,
JB.

igb was updated in 2.6.32-36, closing.
