Subject: netifd: add udhcpc link check to dhcp shell handler script
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=175b2623288957dc7087278d1e78a7eedb077f8f;p=openwrt%2Fstaging%2Fjogo.git

netifd: add udhcpc link check to dhcp shell handler script

Fixes the assumption the busybox udhcpc applet is always enabled; in case
the symbolic link check fails the DHCP shell handler script will exit and
as result the DHCP protocol handler will not be registered in netifd.
