Hi Robert,

I don't think that passing the iface_rec structure directly from the
iscsid internals into a netlink message is a good way to go about this.
It's really big, there's an embedded list_head with user address
pointers that needs to be left out, and there are 32/64-bit layout
differences.

Let me take a look at how you're proposing using this info for iSER, if
it makes sense I think we should come up with a better designed
structure for passing the information.

Thanks,
Chris
