IB/srp: Support SRP rev. 10 targets
There has been a change in the format of port identifiers between
revision 10 of the SRP specification and the current revision 16A.
Revision 10 specifies port identifier format as
lower 8 bytes : GUID upper 8 bytes : Extension
Whereas revision 16A specifies it as
lower 8 bytes : Extension upper 8 bytes : GUID
There are older targets (e.g. SilverStorm Virtual Fibre Channel
Bridge) which conform to revision 10 of the SRP specification.
The I/O class of revision 10 is 0xFF00 and the I/O class of revision
16A is 0x0100.
For supporting older targets, this patch:
1) Adds a new optional target creation parameter "io_class". Default
value of io_class is 0x0100 (i.e. revision 16A)
2) Uses the correct port identifier format for targets with IO class
of 0xFF00 (i.e. conforming to revision 10)
