Hi,

> mpd4.1!

Thank you very much, great software!

I testing it now and have some bug reports...

I have set netflow node <nodename> option in mpd.conf to attach to
existing ng_netflow node
---
default:
 load psrv1
 load psrv3
 ...
pppoe:
 ...
 set netflow node netflow
 set netflow export 172.16.2.35 9996
 ...
psrv1:
 new -n -i ng1 pppoe1 pppoe1
 load pppoe
psrv3:
 new -n -i ng2 pppoe2 pppoe2
 load pppoe
 ...
---
After loading I got:
ngctl list
There are 115 total nodes:

First created bundle stay something special, it don't see
gNetflowNodeName, but rest connected correctly. Later, variable
gNetflowNodeName for first bundle is set and on shutdown mpd not
cleaning corresponding nodes. You can see two nodes from pid 43388...
