New Revision: 192706
URL: http://svn.freebsd.org/changeset/base/192706
Log:
NVIDIA MCP controllers have no Rx buffer alignment restrictions.
Remove PAGE_SIZE alignment used in Rx buffer DMA tag creation. The
alignment restriction was used in old local jumbo allocator and
nfe(4) switched to UMA backed page allocator for jumbo frame.
This change should fix jumbo buffer allocation failure.
