So if_tx_rdy() so
the ENOBUFS is very typical with UDP applications that try to
send as fast as possible (e.g. the various network test utilities
in ports), and as i said in a previous message, putting up a mechanism to
pass around queue full/queue not full events is expensive because
it might trigger on every sing

hm I'm sure I've seen this somewhere before..
ah it's in -current...
in /usr/src/sys/dev/lmc
the version there DOES support netgraph
but I don;t know if it's well maintained..
I'll have to look at it sometime.

Can anyone tell me what network monitoring tools are
available on freebsd suitable for monitoring things
like frame size,frames per second,frame no. e.t.c when
streaming videos are received though the network.
Thanks,

Yahoo!
are you running dhclient or routed?

I am trying to get dnscache running with IPv6 patches.
dnscache binds to the IPv6 unqualified address "::". This works fine
and I get (from netstat)
udp46 0 0 *.53 *.*
As the sending address the IPv6 unqualified address "::" is used, also.
As long as I only send q

You only need to use unnumbered interfaces on one local link,
so you are ok.. you can use static routes to get to and from that site..
and leave BGP to handle the double homed links to the Internet.

Quoting route(8):

This is just a nit, but it seems to me that although the code
in tcp_reass() counts completely overlapping packets via the
statistics tcps_rcvduppack and tcps_rcvdupbyte, it does NOT
count partially overlapping packets as it should with
tcps_rcvpartduppack and tcps_rcvpartdupbyte.

hmm, we looked at how other protocols handled the ENOBUFS case from
ip_output.
tcp_output calls tcp_quench on this error.
while the interface may not be able to send any more packets than it does
currently,
The driver is lmc. The version from the SBEI (formally LanMedia) web site
does not support netgraph. Their support claims to have one (or will have
one I forget). I want to hold off on NG at the moment.
As for what I'm doing. In this case, I have 4 of these PCI cards. I
