Technical description

In the Linux kernel, the following vulnerability has been resolved:

octeontx2-pf: QOS: Refactor TC_HTB_LEAF_DEL_LAST callback

This patch addresses below issues,

1. Active traffic on the leaf node must be stopped before its send queue

is reassigned to the parent. This patch resolves the issue by marking

the node as 'Inner'.

2. During a system reboot, the interface receives TC_HTB_LEAF_DEL

and TC_HTB_LEAF_DEL_LAST callbacks to delete its HTB queues.

In the case of TC_HTB_LEAF_DEL_LAST, although the same send queue

is reassigned to the parent, the current logic still attempts to update

the real number of queues, leadning to below warnings

New queues can't be registered after device unregistration.
