From 1684842147677a1279bcff95f8adb6de9a656e30 Mon Sep 17 00:00:00 2001 From: Hariprasad Kelam Date: Thu, 23 May 2024 13:06:26 +0530 Subject: [PATCH] Octeontx2-pf: Free send queue buffers incase of leaf to inner There are two type of classes. "Leaf classes" that are the bottom of the class hierarchy. "Inner classes" that are neither the root class nor leaf classes. QoS rules can only specify leaf classes as targets for traffic. Root / \ / \ 1 2 /\ / \ 4 5 classes 1,4 and 5 are leaf classes. class 2 is a inner class. When a leaf class made as inner, or vice versa, resources associated with send queue (send queue buffers and transmit schedulers) are not getting freed.
