Hi,
thanks for answers.

I'm still writing to this list because nfs-rdma-devel at lists.sourceforge.net
seems to be dead... :(

I pulled Tom's tree from new url and build a kernel. then I downloaded OFED
from http://www.mellanox.com/downloads/NFSoRDMA/OFED-1.2-NFS-RDMA.gz, however
ofa-kernel fails to build. whatever I do I always got in ofa-kernel:

make[1]: Entering directory `/usr/src/ib/xprt-switch-2.6'
test -e include/linux/autoconf.h -a -e include/config/auto.conf || (            \
echo;                                                           \
echo "  ERROR: Kernel configuration is invalid.";               \
echo "         include/linux/autoconf.h or include/config/auto.conf are missing.";      \
echo "         Run 'make oldconfig && make prepare' on kernel src to fix it.";  \
echo;                                                           \
/bin/false)

obviously, doing 'make oldconfig && make prepare' does not help. anyway, above
mentioned files do exist:

# ls -la /usr/src/ib/xprt-switch-2.6/{include/linux/autoconf.h,include/config/auto.conf}
-rw-r--r--  1 root root 10156 Jan 25 17:42 /usr/src/ib/xprt-switch-2.6/include/config/auto.conf
-rw-r--r--  1 root root 14733 Jan 25 17:42 /usr/src/ib/xprt-switch-2.6/include/linux/autoconf.h

despite of above, compilation continues but fails with:
