Description Landon Fuller 2015-09-26 23:00:35 UTC 
Created attachment 161449 [details]
if_ndis disable BUS_DMA_ALLOCNOW

ndis_attach_pci() unnecessarily passes BUS_DMA_ALLOCNOW when allocating its parent DMA tag; this eager allocation can trigger ENOMEM, preventing attachment.

Attached is a tiny patch removing the eager-allocation flag. With this, I'm able to use NDIS drivers.
