[PATCH 19/39] net/dev: replace schedule_timeout() with msleep()

[Nishanth Aravamudan <nacc@xxxxxxxxxx>]

Hi,

Please consider applying.

Description: Use msleep() instead of schedule_timeout() to guarantee the task
delays as expected. The current code uses TASK_INTERRUPTIBLE, but does not
respond to signals, so msleep() should be ok.
