When have you guys actually hit this? What tools and what version does this?
I believe we had run into this case in the past by not specifying the
ifacename parameter in a static node but use transport of bnx2i. I
would have to go back and revisit that for verification. But its a
scenario our driver has supports for in the past. The jumbo MTU support
was added to the shost case a while back. Adding this is more for
completeness.
Hey,
Let me know what version is doing this next time you see it (do not
waste time on it now). We used to support it a long time ago, but the
current tools do not now.
We took it out a long time ago, because the sysfs code and a bunch of
other things do not handle if the session were to move hosts (like if we
were in recovery and disconnected then reconnected using a different
host). Pointers and refcounting goes kablewy. Other drivers fail in
ep_connect if a shost is not passed in.
