From 93f763c28a8b7070ea2730c651a954e120c807bd Mon Sep 17 00:00:00 2001 From: Lai Peter Jun Ann Date: Mon, 18 Dec 2023 15:51:32 +0800 Subject: [PATCH] net: stmmac: fix incorrect flag check in timestamp interrupt commit bd7f77dae69532ffc027ee50ff99e3792dc30b7f upstream. The driver should continue get the timestamp if STMMAC_FLAG_EXT_SNAPSHOT_EN flag is set.
