[BusyBox] udhcp and SOCK_RAW

[Simon Posnjak]

Hi,

I have the next problem with udhcpc from busybox 1.00-pre3 (it allso happens 
with 1.00-pre0). I run the the client as /sbin/udhcpc -i eth1 and it gets the 
IP as:

Bringing up the eth0 interface...client (v0.9.9-pre) started
udhcpc[137]: client (v0.9.9-pre) started
Sending discover...
udhcpc[137]: Sending discover...

SIOCDELRT: No such process

adding dns 193.189.160.12
[  OK  ]

After some time the client says:

udhcpc[159]: Sending renew...
udhcpc[159]: FATAL: couldn't listen on socket, Protocol not available

tcpdump looks like this:

hlod:~ # tcpdump -i eth0
