distributions but must be installed separately via the OFED package. The patch
below makes it easier to compile SCST-SRPT with the OFED kernel headers by
disabling the backported <linux/scatterlist.h> macro's when compiling with
OFED kernel headers. OFED namely has its own set of backported macro's. OFED
kernel headers are detected via the preprocessor symbol
__BACKPORT_LINUX_SCATTERLIST_H_TO_2_6_23__, which is defined in the OFED
header file <linux/scatterlist.h> only. This patch does not have any effect
when compiling SCST on a system where OFED has not been installed.
