Robert Watson 1f87450e8b Change net.isr.direct from defaulting to 0 to 1 in 7-CURRENT. This 
enables direct dispatch of the network stack from the device driver
ithread, enabling input path parallelism by default when multiple
interfaces are present.

The strategy for network stack parallelism is something being actively
discussed, and this is just one of several possible (and perfectly
reasonable) strategies, but has the distinct advantage of reducing the
number of context switches and preemptions significantly, resulting in
higher efficiency in many cases.  In some caes, this may reduce
network stack parallelism due to work not being deferred from the
ithread to the netisr.  Therefore, the strategy may change in the
future, but this offers a reasonable first pass and enabling
parallelism while maintaining strong ordering.

Hopefully this will trigger lots of nice new bugs.

This change is not intended for MFC.
