> 
> By the commit 72ddef0506da ("igb: Fix oops caused by missing queue
> pairing"), the IGB_FLAG_QUEUE_PAIRS flag can now be set when changing the
> number of queues by "ethtool -L", but it is never cleared unless the igb
> driver is reloaded.
> This patch clears it if queue pairing becomes unnecessary as a result of
> "ethtool -L".
