This is the second issue reported about the BEV code in the last couple 
of weeks.

I don't know much (anything) about the BEV code however I did notice a 
define for  DEBUG_ROMPREFIX that you may want to try enabling.  I have 
never enabled it so I really don't know what it does.

Yes, I would think that a 10Gb card would have high ram demands.  The 
use of allot and forget should be fine.  I used them for a while with 
the r8169 driver without any issue.  I removed them simply to be 
consistent with the other drivers.

If the debug setting reports anything please report back.
