He's not aware of the release .. I can ask him to sign off, but I think it's academic (he doesn't care).. I don't think he knows what a sign off means.

I don't know , can I ? This is what Cisco is currently using ..

Because I didn't realize I needed to.. This release is one in about 25 or so similar drivers that I am planning to release.. I wasn't really sure of what I needed to do w.r.t the sysfs interface details. Most of the drivers have them in some form.

I asked the same question when I looked at the driver. It's in wikipedia,
http://en.wikipedia.org/wiki/Content_addressable_memory#Ternary_CAMs
It used for filtering things by 0,1 or wildcard.. In Cisco case "things" is packets.
