fwparam_ibft and IPv6 support

[Shyam...@dell.com]

I see that a couple of ways are being used to get the ibft data from
memory -

1) iscsiadm -m fw
Which relies on /sys/firmware/ibft/* files to create the record
and thus login.
2) fwparam_ibft -b
This relies on opening /dev/mem and getting all the parameters
and thus login

I am seeing a few problems/discrepancies with the fwparam_ibft tool -

1) It is not able to fetch the chap info
2) It lacks IPv6 support.

I believe open-suse and sles are some of the distros using this tool.
Not sure of debian/ubuntu and others.

Hannes - Do you have already fixed patches for these in your suse tree ?
