  Updating the loader to use


As well as disabling HT in the bios fixed the issue. 

I propose the following "fix"

1. Update the man page to denote 

             The maximum number of allocated RSS channels for the Nth adapter.
             If set to 0 or unset, the number of channels is determined by the
             number of CPU cores. This does not scale beyond 32 cores. You need 
             to manually set the hw.sfxge.N.max_rss_channels <=32 before
             driver in a box with more then 32 cores.
