# Purpose : for mtk debug mechanism. agpsd_data_file, mtk_agpsd are used
# to share wifi scan results with AGPS module. netlink_socket is used to
# listen events of wlan driver. udp_socket is used to do ioctl with wlan driver
# kernel-3.18 uses netlink_socket, but kernel-4.4 uses generic netlink_socket

# Date : WK18.17
# Operation : Migration
# Purpose : To allow wlan_assistant monitor /vendor/nvdata/APCFG/APRDEB,
# /storage/sdcard0, /vendor/firmware. Which can help to check if nvram,
# driver config or firmware config file are changed, if yes, will write it
# to wlan driver in time.
