[OpenWrt-Devel] [PATCH v2 2/2] uqmi: Add get-current-settings command-line switch

Sat Aug 8 03:44:38 EDT 2015
Adding --get-current-settings switch which can be used to query
ip-settings among some other useful data obtained from remote end when
connected.
This is mainly useful with modems which do not provide a dhcp server for
nameserver or ip-information (especially in ipv6 networks).
