Michael, Vlad,

The patch above fixes a bug in OFED 1.1 installation scripts. iSER could
be installed only on a specific kernel version of SLES 10. The patch
allows it to be installed on any SLES 10 version (i.e SLERT and future
service packs).

This patch was accepted by Novell. Can you add it to OFED 1.1?

Thanks,
Erez
