Multiple Interfaces with the same IP

[Michael Bretterklieber]

Hi,

it looks like that under 5-stable it's allowed to have different 
interfaces with the same IP, bug or feature?

bash-2.05b# ifconfig ath0 inet 192.168.201.12 netmask 0xffffff00 up
bash-2.05b# ifconfig sk0 inet 192.168.201.12 netmask 0xffffff00 up
bash-2.05b# ifconfig
