When trying to set up an iscsi initiator (in yast) using a bnx2 offload engine,
I wasn't getting very far, see bug#1215621.  

I kept getting this error:

iscsiadm: Could not set host net params (err 29)

I ran iscsiuio with debug level 4 and noticed the following error msg:

Couldn't mmap registers: Invalid argument

After some research, I rebooted the machine with "iomem=relaxed" - now it
works:

anton:~ # iscsiadm -m discovery -P 1 -t st -I eth4-bnx2i -p 10.42.8.10:3260
iscsiadm: Could not set host net params (err 29)
iscsiadm: Connection to discovery portal 10.42.8.10 failed: operation failed
but retry may succeed
