Description of problem:
When setting a static ip using edit of the 'network' menu, you set an ip address, a netmask and a default ip address.  When this is saved in /etc/sysconfig/ifcfg-eth1, the netmask is wrongly set to value of the default gateway.

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


How reproducible:
using 'root' System->administration->network to edit the network device.

Steps to Reproduce:
1. select system->administration->network
2. highlight which device. In my case it is eth1
3. press edit
4. change from dynamic addressing to static addressing
5. set the ip address (ex: 192.168.5.27)
6. set the netmask (255.255.255.0)
7. set the default gateway address (ex: 192.168.5.1)
8. save the configuration

Actual results:
if you reopen the above display, you will see the netmask has been changed
to the value of 'default gateway address'
if you check /etc/sysconfig/ifcfg-eth1, you will see the netmask has been
altered to the value reported in the gui display.

Expected results:
setting the netmask should cause the config to accept the value supplied.
ex: 255.255.255.0
