From 3ceb08838b576b20108d7facf6baa3dbf792afe9 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Mon, 1 Sep 2025 14:12:10 -0700 Subject: net: add helper to pre-check if PP for an Rx queue will be unreadable mlx5 pokes into the rxq state to check if the queue has a memory provider, and therefore whether it may produce unreadable mem. Add a helper for doing this in the page pool API. fbnic will want a similar thing (tho, for a slightly different reason).
