From 20e07e2c3cf310578ef19fb4f1e64dc9832abd9d Mon Sep 17 00:00:00 2001 From: Wong Vee Khee Date: Wed, 17 Feb 2021 17:57:05 +0800 Subject: [PATCH] net: stmmac: Add PCI bus info to ethtool driver query output This patch populates the PCI bus info in the ethtool driver query data. Users will be able to view PCI bus info using 'ethtool -i '. Signed-off-by: Wong Vee Khee Signed-off-by: David S.
