> This series of small patches is meant to resolve a number of

> The second patch uses netif_tx_disable to stop TX queues when

> Third, fixup a typo that resulted in partial sanitization of

> 
> Fourth, remove an ambiguous conditional check that was resulting

> Finally, fix a condition where the napi polling routine exits

Series applied, thank you.
