Happy to sse that Coraid is contributing to the kernel.org initiator!
I have tryed for a while to convince customers of my former company to give AoE a try. After presenting them the technology they had no doubt about AoE superiority over iSCSI. However, they often chose iscsi as it appeared to be the de-facto standard.
IMHO, this is, for a large part, due to the lack of activities in the various opensource implementation. That said this lack of activity is understandable as the specs didn't evolve, so I presume only few work has to be done...
Targets like AoE are realy interresting project, but are now abandonned (partly) because of this I guess.
In any case an activity on the client side is a good news!
Question... is it possible to use Coraid HBA with a Linux target? If so, does it drop the need for the sofware initiator?
Kind regards.

I'm happy to hear that there is now progress on getting the initiator
updated in upstream, hopefully this will help to correct the
assumption that AoE is dead or dying.
Not that I'm very knowledgeable about the storage sector, but it seems
to me that AoEs main problem as a technology is marketing.
I've spoken to other sysadmins that merely go "Huh?" when I tell them
we're running AoE, but many people seem to find the idea interesting
when I explain what it is.
For my part, I can say that I set up AoE on default Debian packages
some time ago, and everything has more or less "Just Worked"(TM) since
then.
Not that my deployment is very fancy or has a high load on it, but
still, AoE brings home the bacon for our part.

Recently there have been a lot of patches from Coraid to the Linux Kernel Mailing List for bringing the kernel.org-distributed driver up to date. For example,
