Question on software-crypt mode.

I am trying to implement software-crypt for ath10k so that it can do crypt
with multiple stations connected to same AP.

I tried using ath9k's approach and just not setting keys, but that does not work at all
(no stations can communicate).

If I basically leave code as is, then secondary stations can associate but never
get DHCP.  I see FCS and hw-crypt errored packets being received from the
ath10k firmware/chip.  This is probably because the chip/firmware decodes the
secondary station's packets with the first station's keys.
Transmitted packets (as sniffed from the AP) do appear fine.

I was thinking to just take all fcs and/or crypt-errored packets in
the receive path and somehow send them up the stack for the software-crypt
layer to (re)decrypt.  I think I have managed to get ath10k to send them
up, but still DHCP does not complete.

Does anyone have any suggestions for things to try or code to look at in
