[Impact]
Yellow carp w/ SW CM bi-directional interdomain communication may have some
problems that the response packets are lost sometimes within the stipulated
time.
[Fix]
Enable the retry by increasing retry count from 1 to 4.
The patch is in linux-next (tag next-20211007) and can be found @ https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/drivers/thunderbolt/ctl.c?id=641cdbea7635be3a177dbdf81356ccb16f3769e3
[Test]
This is requested and tested by AMD.
[Where problems could occur]
Low risk. This only affects small number of AMD systems that would excess the
time. Systems without problems won't be affected.
