You do not need jail to limit output of ifconfig.
Each network interface in FreeBSD can belong to one or more interface groups.
First add all your interfaces except of ng* to some new interface group with ifconfig(8), then use:

alias ifconfig='/sbin/ifconfig -g groupname'

Or create new short alias ifc='/sbin/ifconfig -g groupname'
for short output.
