so I applied this, but now I'm starting to wonder about how ULPs would
use this. As I understand things, this is really working around the
fact that cxgb3's get_dma_mr() implementation is limited to 4G. But how
can a ULP know if a given device has the 4G limitation? For every other
device (modulo iw_nes's 1 TB limitation) get_dma_mr works fine for local
DMA. Thoughts?
