From a3984578bf0ed578085bd3c382867c0121bb1534 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Sat, 28 Apr 2018 22:19:15 +0200 Subject: [PATCH] r8169: improve rtl8169_set_features __rtl8169_set_features is used in rtl8169_set_features only, so we can inline it. In addition: - Remove check (features ^ dev->features), __netdev_update_features check's already that requested features differ from current ones. - Don't mask out unsupported flags, there's no benefit in it.
