From bd2948d2581ebd31745c1b7094a470513789555f Mon Sep 17 00:00:00 2001 From: Laurent Vivier Date: Wed, 21 May 2025 11:22:35 +0200 Subject: [PATCH] virtio_net: Cleanup '2+MAX_SKB_FRAGS' Improve consistency by using everywhere it is needed 'MAX_SKB_FRAGS + 2' rather than '2+MAX_SKB_FRAGS' or '2 + MAX_SKB_FRAGS'. No functional change.
