Author: yongari Date: Mon May 25 00:56:01 2009 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.
