Unfortunately there's no timeout for how long a packet can sit on the TX ring after completion before an interrupt is generated, and we want to have a threshold that's larger than one packet per interrupt. So we have to have a timer that occasionally cleans the TX ring even though there hasn't been an interrupt. Instead of setting up a dedicated timer for this, just clean it in the NAPI poll routine instead. Signed-off-by: Olof Johansson --- I know I got this rejected last time it was submitted, but no answers with suggestions on how to handle it better. I'm all ears if there's a better way. (I noticed that Intel's new ixgbe driver does the same thing).
