- Fix a critical bug in NdisMGetDmaAlignment which was causing every NIC driver calling this function to crash because we thought we were passed an NDIS_DMA_BLOCK handle when in fact we receive an NDIS_MINIPORT_BLOCK handle
- Fixes RTL8169 and 3Com NICs (and probably several more) [bug 6651 and bug 4330]
