-  marvell,powertable => Specify external power table. If your device needs external power table, you must provide the power table via this parameter, otherwise the Tx power will be pretty low.

+
+* How to replace mwlwifi on your current LEDE/OpenWrt build:
+
+    a. Establish a symbolic link to your working mwlwifi directory with current mwlwifi package name under directory "dl":
+
+    #ls -l mwlwifi*
 
-  root@lede:/# echo 2 > /proc/irq/irq number of phy0 or phy1/smp_affinity => use CPU1
+    lrwxrwxrwx 1 dlin dlin      48  mwlwifi-10.3.2.0-20170110 -> /home/dlin/home2/projects/github/mwlwifi
+
+    -rw-r--r-- 1 dlin dlin 4175136  mwlwifi-10.3.2.0-20170110.tar.xz
+
+    b. Back up original mwlwifi package and tar your working mwlwifi to replace oringial mwlwifi package:
+
+    #tar Jcvf mwlwifi-10.3.2.0-20170110.tar.xz mwlwifi-10.3.2.0-20170110/.
+
+    c. You can use "make V=s" to build the whole image or "make V=s package/kernel/mwlwifi/compile" to build mwlwifi package.
+
+    d. Due to package version is the same as previous one, you need to add option "--force-reinstall" when you use "opkg" to update mwlwifi package on your device.
