OK, I will fix here in next update.

+The PPE driver files in drivers/net/ethernet/qualcomm/ppe/ are listed as below:
+
+- Makefile
+- ppe.c
+- ppe.h
+- ppe_config.c
+- ppe_config.h
+- ppe_debugfs.c
+- ppe_debugfs.h
+- ppe_regs.h
If somehow new source files were added, should the list above be updated to
keep up?
Yes, the list will be updated when new files added in the following PPE
MAC and EDMA patch series.
+Enabling the Driver
+===================
+
+The driver is located in the menu structure at:
+
+ -> Device Drivers
+ -> Network device support (NETDEVICES [=y])
+ -> Ethernet driver support
+ -> Qualcomm devices
+ -> Qualcomm Technologies, Inc. PPE Ethernet support
Literal code block should format above nicer, but plain paragraph is fine.
OK, I will use Literal code block by using "at::" to replace "at:" here.
hope it is fine.
+
+If this driver is built as a module, we can use below commands to install and remove it:
+
+- insmod qcom-ppe.ko
+- rmmod qcom-ppe.ko
"If the driver is built as a module, the module will be called qcom-ppe."
(I assume that readers know how to insert/remove modules).
OK, I will modify this sentence in next update.
Thanks.
