[package] ppp:
- patch pppd to support named interfaces (e.g. "pppoe-wan") - use named interfaces when bringing up 3g, pptp, ppp or pppoe connections - get rid of unit count logic - shutdown pppd when ifdown is invoked - bump package revision git-svn-id: svn://svn.openwrt.org/openwrt/trunk@21283 3c298f89-4303-0410-b956-a3cf2f4a3e73
