Log Message:
Implement BPF_COP/BPF_COPX instructions in the misc category (BPF_MISC)
which add a capability to call external functions in a predetermined way.
It can be thought as a BPF "coprocessor" -- a generic mechanism to offload
more complex packet inspection operations. There is no default coprocessor
and this functionality is not targeted to the /dev/bpf. This is primarily
targeted to the kernel subsystems, therefore there is no way to set a custom
coprocessor at the userlevel.
