>Description:
When configuring multiple network interfaces in /etc/rc.conf, dhcpcd only configures the first interface.
>How-To-Repeat:
1)
Have a machine with multiple network interfaces (or configure a VM with multiple network interfaces).

2)
Put this in /etc/rc.conf (replacing wm0 and wm1 with appropriate interface names):
ifconfig_wm0=dhcp
ifconfig_wm1=dhcp
net_interfaces="wm0 wm1"

3)
Reboot

4)
run "dhcpcd --dumplease" and observe that it only has a lease for the first interface in the list above
>Fix:
Don't configure this manually, just do "dhcpcd=yes" in rc.conf.  This might have side effects if you have even more interfaces and you don't want to configure all of them.
