-Subject: [PATCH 6/8] net: stmmac: create one debugfs dir per net-device
-
-stmmac DebugFS entries are currently global to the driver. As a result,
-having more than one stmmac device in the system creates the following
-error:
-* ERROR stmmaceth, debugfs create directory failed
-* stmmac_hw_setup: failed debugFS registration
-
-This also results in being able to access the debugfs information for
-the first registered device only.
-
-This patch changes the debugfs structure to have one sub-directory per
-net-device. Files under "/sys/kernel/debug/stmmaceth" will now show-up
-under /sys/kernel/debug/stmmaceth/ethN/.
