Hi!
I'm sending data (with UDP/IP in an in-kernel data-path) too fast for the
NIC, and the queue is filled up making the system to dropp packets with
error ENOBUFS. Both ip_output and if_etheroutput checks the
ifp->if_snd.ifq_maxlen which is by default
IFQ_MAXLEN (50)!!?? Is this value increased somewhere if the queue starts
to fill, because I printed this value and is says 511.....
Could it help to increase this value?
Thanks,
-ph
