Bug description:
[Impact]
There were BUG: scheduling while atomic: ip/1210/0x00000200 appearing
on xenial/hwe with the tg3 ethernet driver when running on rumford instance.
Probably some performace degradation as the driver was trying to sleep while
holding a spinlock.
There also was cluttering of the kernel log with stack traces.
[Fix]
Change usleep_range -> udelay which is safe to call from atomic
contexts.
[Test]
Compile tested only. Should see this resolved in the next cycle on
xenial/hwe rumford instance.
[Where problems could occur]
Not much regression potential as the correct delay call is now being
called.
--------------------------------------------------------------------------
There is a bug being triggered on a usleep within the tg3 driver with
xenial/linux-hwe 4.15.0-197.208~16.04.1 on rumford.
This has been observed in multiple cycles during boot-testing.
