*Project summary
The project goal is to support multiqueue network interface on BPF,
and provide interfaces for multithreaded packet processing using BPF.
Modern high performance NICs have multiple receive/send queues and RSS
feature, this allows to process packet concurrently on multiple
processors.
Main purpose of the project is to support these hardware and get
benefit of parallelism.

Here's status update from last week:
*Implementing test programs
http://p4web.freebsd.org/@@196076?ac=10
I'm implementing these three program:
- test_ifqueue
- test_sqbpf
- test_mqbpf

test_ifqueue is for testing queue length/queue affinity ioctls.
test_sqbpf and test_mqbpf is for comparing bpf performance between
non-multiqueue bpf and multiqueue bpf, also for testing bpf multiqueue
ioctls.

Right now I only submitted test_ifqueue and test_sqbpf, test_mqbpf is
still under testing.
