Subject: uqmi: do not block proto handler if modem is unable to registrate
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=dec1bfa0f48d43174921d1a1357a4842f9ba0cf6;p=openwrt%2Fstaging%2Fnbd.git

uqmi: do not block proto handler if modem is unable to registrate

QMI proto setup-handler will wait forever if it is unable to registrate to
the mobile network. To fix this stop polling network registration status
and notify netifd. Netifd will generate then a "ifup-failed" ACTION.
