From 086ca23d03c0d2f4088f472386778d293e15c5f6 Mon Sep 17 00:00:00 2001 From: Chunhao Lin Date: Wed, 31 Jan 2018 01:32:36 +0800 Subject: [PATCH] r8169: fix RTL8168EP take too long to complete driver initialization. Driver check the wrong register bit in rtl_ocp_tx_cond() that keep driver waiting until timeout. Fix this by waiting for the right register bit. Signed-off-by: Chunhao Lin Signed-off-by: David S.
