1. Removes the need to walk the IRQ/Device list to determine
who triggered the IRQ.
2. Improves scalability (up to several times performance
improvement for cases with 10s of devices).
3. Improves UML baseline IO performance for one disk + one NIC
use case by up to 10%.

1. Provides infrastructure for vector IO using recvmmsg/sendmmsg.
1.1. Multi-message read.
1.2. Multi-message write.
1.3. Optimized queue support for multi-packet enqueue/dequeue.
1.4. BQL/DQL support.
2. Implements transports for several transports as well support

af_packet family in the kernel resulting in it being
stuck in a -ENOBUFS loop.
This results in TX/RX TCP performance ~ 2-3 times higher

Sorry all,
I fat fingered this one, will resubmit once I get back home and redo it
(I am traveling all day).

Patches 1 and 2 are the same as before, patch 3 adds TSO, GRO and
full scatter gather support as well as ability to on/off all
features from commandline and/or ethtool where applicable.
The result from patch 3 is 5.6Gbit on tcp throughput using the
tap/raw driver on a 3.5GHz AMD A4 desktop.
