Dear Christopher,

Thank you for your patch.

In the summary, I’d add specific values:

igc: Reduce retry count to from 100 to reasonable 8

Setting the retry count to 8x is more than sufficient. 100x is unreasonable
 and would indicate broken hardware/firmware.

I’d remove the leading space.

Is using a 100 causing so much more delay and debugging an issue is harder?

Is there data available that no more than 8 retries were needed?
