Yes, it is a transmitter side problem, and A-MSDU on IBSS
is disabled by default in all ath10k firmware versions that I am aware of.

I was hoping there might be a way to allow A-MSDU + IBSS + ath10k
to work in future kernels without applying out-of-tree
kernel hacks.  This would let people with appropriate firmware
enable IBSS + A-MSDU for added performance in cases where they
knew the peer could support the needed work-around.

I don't think it is worth a lot of effort, but if it were relatively
simple to fix, then maybe it is worth it.
