commit 43dfd1169cc07128c2dc3fecd89fc2f34bf35b15
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I5L6E7

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=43dfd1169cc07128c2dc3fecd89fc2f34bf35b15

--------------------------------

[ Upstream commit 0bb05067 ]

If ADQ is enabled for a VF, then actual number of queue pair
is a number of currently available traffic classes for this VF.

Without this change the configuration of the Rx/Tx queues
fails with error.
