From b4010af981ac8cdf1f7f58eb6b131c482e5dee02 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Wed, 1 May 2019 21:54:28 +0200 Subject: [PATCH] net: phy: fix phy_validate_pause We have valid scenarios where ETHTOOL_LINK_MODE_Pause_BIT doesn't need to be supported. Therefore extend the first check to check for rx_pause being set. See also phy_set_asym_pause: rx=0 and tx=1: advertise asym pause only rx=0 and tx=0: stop advertising both pause modes The fixed commit isn't wrong, it's just the one that introduced the linkmode bitmaps.
