>Description:
When trying to implement ipfw with bridging and dummynet, it isn't
stable at all. I tried 4.2 and received a panic whenever I enabled net.link.ether.bridge_ipfw.
Same thing in 4.1. I then went back to 3.5.1 and it will run, however
after running for a few minutes it quits responding. 

>How-To-Repeat:
Enable bridging ipfw and dummynet.

>Fix:
Only on 3.5.1. Issue a sysctl -w net.link.ether.bridge_ipfw=0 then
wait a few seconds then issue sysctl -w net.link.ether.bridge_ipfw=1 and
it starts responding again for a few minutes then dies again.
On 4.1 and 4.2 I couldn't determine a fix. I've tried several different
types of network cards, both PCI and ISA to no avail.

 Hi,
 
 this bug has hopefully been fixed in -STABLE (after 4.2 was released).
 An update should help you.

 Thank you, Thomas!!!!!
 That did the trick! I upgraded to 4.2-STABLE and the ipfw, bridging and
 dummynet work like a charm! I am once again a happy camper!
