[PATCH net-next 5/6] net: ipa: change stop channel retry delay

From: Alex Elder
Date: Wed Jan 13 2021 - 12:17:46 EST


If a GSI stop channel command leaves the channel in STOP_IN_PROC
state, we retry the stop command after a 1-2 millisecond delay.

I have been told that a 3-5 millisecond delay is a better choice.
