Description of problem:
ifup-ippp does not pass the netmask (if set) to ipppd. This results in an 
incorrect netmask if the device is connected (or was connected before).

This is a bug in initscripts (because ifup-ippp is located there), but i did 
file this bug here, because the maintainer of ifup-ippp is probably the same as 
for isdn4k-util. If not please reassign.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. <Set netmask>
2. <Connect>
3. route
	

Actual Results:  Netmask is not as defined in the ifcfg-ippp? file

Expected Results:  Netmask as defined in the ifcfg-ippp? file
