WCN3620 can asynchronously send two new kinds of indication message,
since we can't handle them just accept them quietly.

v2: used one break for both in the second stanza

wcn3620 has a new message structure for the reply to some hal
commands.  This patch adds the struct and helper routine that
uses it if the chip is wcn3620, or falls back to the old
helper routine.

We don't know what to do with the candidate list he sends back,
but we can at least accept and ignore it nicely instead of dying.

Hi Fengwei,

There are two "From" lines in this and a couple of the other patches,
can you remove one?  (Not sure if git-am automatically strips the second
or not.)

It's unclear from the changelog -- is it safe to call
wcn36xx_smd_rsp_status_check_v2 on the 3660/3680 as well?

Is wcn36xx_smd_rsp_status_check() still needed?

Ok, disregard my question on the other patch, for some reason I
read them out of order.  It looks like this should work ok with
non-3620 chips.

Even on 3620, not all cmds switch to wcn36xx_smd_rsp_status_check_v2.
And I don't think wcn36xx_smd_rsp_status_check_v2 should bind to 3620 (it
may be related with firmware).

In patch v2, the wcn36xx_smd_rsp_status_check_v2 is not bind to 3620. If
you could test on none-3620 platform (I don't have none-3620 plafrom), that
will be great.

I will send out patch v2 soon which drive the build error and the comments
from you. Thanks a lot for reviewing.

Yin, Fengwei

I had to introduce this on one of my 3680 devices recently to silence
the error described originally by Andy. So it not only seems safe but
seems required. But still, based on how the code was written this
doesn't seem to be the case on all versions of the firmware or all
chips(?)

Thanks for the information. It confirm my thought that the change sticks
to new firmware instead of specific platform.

But we couldn't tell which version of firmware need this new format. Andy's
original change has two conditions to use the new format:
1. The platform is 3620. - this should be removed because you need the same
    change for 3680. And patch v2 already remove it.

2. The packet size from firmware is larger than old response size. I suppose
    this one works in most case.

Oops, sorry.  I can confirm my hardware uses this format.

Turns out, in my backports snapshot I was already carrying a patch for it:

Actually, this patch was using the v1 and DragonBoard needs v2 for trigger_ba.
And I want to know whether the change from Andy could work on the platform
which is using v1.

Can you try this change on your platform? Thanks.

I'm not sure I understand -- if you look at the right side of the diff
for the patch "wcn36xx: Parse trigger_ba response properly", it is changing
wcn36xx_smd_rsp_status_check() to wcn36xx_smd_trigger_ba_rsp(), whose
definition is the same as wcn36xx_smd_rsp_station_check_v2() as far as I can
tell.  Or am I missing something?

Yes. Exactly. So your platform is using the v2 format as well. We may not need
to care the v1 format too much. Thanks.

Hi Yin,

Yes, it seems like response is FW specific other than chip spesific.
