Missed in SRCTOP conversion in r314651. MFC with: r314651 r318440: Normalize SYSDIR on SRCTOP instead of .CURDIR This is being done to simplify pathing for CFLAGS and source files. Add a facility for devices, specifically network interfaces, that require 2003-07-15T08:59:38Z Hartmut Brandt harti@FreeBSD.org 2003-07-15T08:59:38Z urn:sha1:7e9024cdd9a555f05fef1a872eb05e0d4fefebc1 large to huge amounts of small or medium sized receive buffers. The problem with these situations is that they eat up the available DMA address space very quickly when using mbufs or even mbuf clusters. Additionally this facility provides a direct mapping between 32-bit integers and these buffers. This is needed for devices originally designed for 32-bit systems. Ususally the virtual address of the buffer is used as a handle to find the buffer as soon as it is returned by the card. This does not work for 64-bit machines and hence this mapping is needed.
