Dear Karen, dear Jan,
Thank you for the patch.

From: Jan Sokolowski <[email protected]>
TC queues needs to be correctly updated when the number of queues on
need
a VSI is reconfigured, so netdev's queue and TC settings will be
dynamically adjusted and could accurately represent the underlying
hardware state after changes to the VSI queue counts.
Please document the test configuration, and how to test/verify your change.

ndo_setup_tc")
