[ofa-general] Re: [PATCH for-2.6.27 1/2] RDMA/Core: Add local dma lkey support.

[Roland Dreier]

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?
