From b1cb441916296af74c791e97d43d6e972ed9a723 Mon Sep 17 00:00:00 2001 From: Joe Damato Date: Fri, 14 Feb 2025 21:12:30 +0000 Subject: [PATCH] netdev-genl: Add an XSK attribute to queues Expose a new per-queue nest attribute, xsk, which will be present for queues that are being used for AF_XDP. If the queue is not being used for AF_XDP, the nest will not be present. In the future, this attribute can be extended to include more data about XSK as it is needed.
