Remove netmask configuration and hardcode instead

Browse Source 
I initially planned to entirely remove the netmask configuration.
However, in specific configurations, e.g. in 4G Rfsim with feMBMS,
routing does not seem to work anymore using these commands:

  iperf -B 10.0.2.2 -s -u -i1
  iperf -c 10.0.2.2 -B 10.0.2.1 -u -t 30 -b 2.00M -i1

Therefore, we simplify by hardcoding the netmask to /24, which allows
the above to work.
