Netgraph ng_bridge status message missing last three values?

[Guy Helmer]

I'm diagnosing a system that uses the Netgraph ng_bridge node to bridge 
two Ethernet segments and the system seems to stop passing traffic at 
randomly-triggered points (somewhat annoying for a system half a world 
away behind a very restrictive firewall :-)

I've installed a cron job to dump the Netgraph bridge status messages to 
a log file every few minutes.  However, I've found that the ng_bridge 
status message looks like this:

 > ngctl msg bnet0: getstats 0
STATS=Rec'd response "getstats" (4) from "[10]:":
Args:   { recvOctets=474229151 recvPackets=3322699 recvMulticast=128640 
recvBroadcast=105813 recvUnknown=2372 xmitOctets=516954216 
xmitPackets=2968420 xmitMulticasts=8 xmitBroadcasts=339 }

but to aid diagnosis I would really like to see several values that, 
according to ng_bridge.h, are in the stats structure, including
recvRunts, recvInvalid, loopDrops, loopDetects, and memoryFailures.  It 
looks like all the code is there to report the values of these 
variables, but I can't seem to find anything that is dropping these 
variables from ngctl's output.

Any help is greatly appreciated,
Guy
