calling all WiFi users

[Joe Talbott]

Hi,

Anyone using WiFi on DragonFly BSD please test the following branch:

git://leaf.dragonflybsd.org/~josepht/dragonfly.git mjumpagesize

This adds jumbo cluster support needed for Intel WiFi NICs and removes
the requirement for non-Intel WiFi NIC users to rebuild their kernel
with MCLSHIFT set to 11.

I plan on committing this in a week if no issues arise.  I've been
running this code for several weeks without issues.

Thanks,
Joe
