Why show these special connections if the user cannot interact with or
shape the stream at all like normal ones?
This whole "make it look normal" argument is entirely bogus because
none of the standard Linux networking facilities can be applied to
these things.
And I even wonder, these days, if you probably get %90 or more of the
gain these "optimized" iSCSI connections obtain from things like LRO.
And since LRO can be done entirely in software (although stateless
HW assistence helps), it is even a NIC agnostic performance improvement.
