This is very strange, i'm sure i'm doing something wrong.

I have rmem_max set to 272144, i use setsockopt to set the
options for the socket, namely SO_RCVBUF, this i set to 1048576.

The socket i create with  socket(PF_NETLINK,SOCK_RAW,NETLINK_FIREWALL).

(this is basicallly all in libipq, i've not changed more than the
rcvbuf).

now the strange thing is, when receiving data, i get IPQ_ERR_TIMEOUT's,
this being basically impossible imho because of the high packet rate.

after these timeouts, i get no data at all... data hits the queue, but
my small proggie doesn't get any (using a 1/4 timeout), funny enough i
don't get IPQ_ERR_TIMEOUTS... *shrug*... any help would be very much
appreciated!
