Hi.

I'm not of much help in reviewing the code and/or making code
suggestions.  Instead, I'm trying to build the driver as we've
several new servers with ISP4010 adapters, which should work
somehow... ;)

Except of the obvious prob wrt ql4_netlink.h file which you
already fixed by subsequent patch.. well....

....Ok.  I'm new in this area (just joined open-iscsi list).
And my first question is: which [i]scsi implementation you
were used as a base for this driver?

I've tried against curren open-iscsi svn repo, against
scsi-misc kernel git tree, and against open-iscsi-1.0-485
tarball.  Whch all are mostly similar (in API anyway).
ql4 driver does not compile - even after "fixing" some
"missing" #includes (like iscsi_if.h defining most of
the ISCSI_* constants used in ql4_os.c), there are alot
of functions missing (iscsi_{add,remove,free}_session()
etc), undeclared structures used (*dscvr*) etc.

What was used as a base for the work?

And also -- how ql3 driver is related to this ql4 one?
Does it (ql4) require ql3 to be compiled/loaded as well?
(The question is because, as it seems, the card represents
as two PCI (sub)devices - one is ethernet controller and
another is "network controller", like this:

04:04.0 Ethernet controller: QLogic Corp. QLA3010 Network Adapter (rev 05)
04:04.1 Network controller: QLogic Corp. QLA4010 iSCSI TOE Adapter (rev 05)
)

Thanks.
