From 132857d9124c853c105acf96b557ce866c044970 Mon Sep 17 00:00:00 2001 From: Maxim Mikityanskiy Date: Fri, 30 Sep 2022 09:28:58 -0700 Subject: net/mlx5e: Use non-XSK page allocator in SHAMPO The SHAMPO flow is not compatible with XSK, it can call the page pool allocator directly to save a branch. mlx5e_page_alloc is removed, as it's no longer used in any flow.
