Subject: umbim: Allow roaming and partner connections
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=840ce0a65bbb7ba13a547f90cb94452b290475ef;p=openwrt%2Fstaging%2Fthess.git

umbim: Allow roaming and partner connections

Allow registration if the SIM is roaming or partner mode, by adding two
new options to the protocol.

Until now, such registration failed because umbim returns exit codes 4 and
5 for such situations.
