[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 5.16

[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.
