stable inclusion from stable-v6.6.2 commit 4c79c7a4e7fbe63f4cbcd0785e2f3b6ca12d9eb0 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8IW7G
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 5831fc1fd4a578232fea708b82de0c666ed17153 ]
If the queue isolation feature is enabled, the number of queues supported by the device changes. When PF is enabled using the current default number of queues, the default number of queues may be greater than the number supported by the device. As a result, the PF fails to be bound to the driver.
After modification, if queue isolation feature is enabled, when the default queue parameter is greater than the number supported by the device, the number of enabled queues will be changed to the number supported by the device, so that the PF and driver can be properly bound.
