Hi,

On kfreebsd, the udeb for ISC DHCP client fails to set a netmask,
if one was given in the DHCP lease.  This means some hosts on the
local network may be unreachable, perhaps nameservers or something
essential for reaching the Internet.

The patch is very simple:

-            ifconfig $interface inet $new_ip_address $new_subnet_arg \

             route add $new_ip_address 127.1 $metric_arg >/dev/null 2>&1 || true
             for router in $new_routers; do

Where $new_mask is /prefixlen, calculated earlier in the script, or
otherwise it is an empty string.

I've tested this within kfreebsd-amd64 d-i as a local udeb.

Thanks!
