From 7a67e11d901e17c3222d226c345be555106faae6 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Wed, 19 Sep 2018 22:00:24 +0200 Subject: [PATCH] r8169: simplify RTL8169 PHY initialization PCI_LATENCY_TIMER is ignored on PCIe, therefore we have to do this for the PCI chips (version <= 06) only. Also we can move setting PCI_CACHE_LINE_SIZE. Signed-off-by: Heiner Kallweit Signed-off-by: David S.
