Eric,
Yep, that was an option too, but when we realized that libpcap has the
means to add plug-in for non-netdevices (e.g usb, can devices and now we
are thinking to add one for uverbs), it means we can avoid adding tons
of pretty complex code into the kernel driver and happily have simpler
code is user-space, so... why not? will try that 1st.
Or.
