Some features of 802.11ax without central organizing (AP) STA can also be
used in mesh mode. hwsim can be used to assist initial development of these
features without having access to HW.

v6:
* rebased on top of 690c4509e980 ("mac80211_hwsim: Fix a typo in the name
of function 'mac80211_hswim_he_capab()'")
* dropped incorrectly left "Forwarded" tag in commit message
* drop merged mac80211 patch
* drop ath11k patches will go to some special post-upstreaming branch and
will be submitted separately
v5-v1:
* see https://lore.kernel.org/r/20190724163359.3507-1-sven@narfation.org
The patch was checked against hostapd's tests version 05822609d105
("HE: MCS size is always a minimum of 4 bytes") and the pending tshark < 3.1.0
workaround [1]. The latter is only affecting test "wpas_mesh_max_peering".
The other patch [2] I had in my hostapd queue in earlier tests [3] was not
actually needed for hwsim+mesh.

I'm testing this now with a bit newer snapshot: 6a7ce95d752e
("staging/octeon: Fix build error without CONFIG_NETDEVICES").

And with the exact same snapshot of hostap.git.
Without [1] applied, this mac80211_hwsim patch to enable HE meshpoint
results in the following test cases failing:
mesh_secure_ocv_mix_legacy
wpas_mesh_open_ht40
wpas_mesh_max_peering
mesh_secure_ocv_mix_ht
[1] fixes wpas_mesh_max_peering
This leaves following three test cases failing ("Test exception:
Couldn't join mesh"):
mesh_secure_ocv_mix_legacy
wpas_mesh_open_ht40
mesh_secure_ocv_mix_ht
Am I missing a patch somewhere that would be needed to make those pass?
More specific reason for the failures:
wpas_mesh_open_ht40:
nl80211: mesh join (ifindex=3)
* freq=5180
* he_enabled=1
* vht_enabled=0
* ht_enabled=1
* bandwidth=0
wlan0: mesh join error=-1
mesh_secure_ocv_mix_legacy:
same issues on dev1, but dev0 did complete join with a different set of
parameters:
nl80211: mesh join (ifindex=3)
* freq=5200
* he_enabled=1
* vht_enabled=1
* ht_enabled=1
* bandwidth=80
* channel_width=3
* center_freq1=5210
* center_freq2=0
* Mesh ID (SSID)=wpas-mesh-sec
* flags=0000000D
* IEs - hexdump(len=22): 30 14 01 00 00 0f ac 04 01 00 00 0f ac 04 01 00 00 0f ac 08 c0 40
nl80211: mesh join request send successfully
(and same for mesh_secure_ocv_mix_ht)
So is that missing of vht_enabled=1 from some configurations the problem
here and if so, would you be able to point me to a hostap.git patch that
addresses this?

No, these also failed for me without the mac80211_hwsim patch [3] in a full
test run. And thus not analyzed further by me.
Interestingly, they don't fail (without the hwsim patch) when running them
without the full test suite.

No, there is no hostap.git patch here. There was one in the past in
patchwork [4] but there were concerns by John. So if you reapply the patch
then you will see that it doesn't fail anymore.

So as a compromise, I can can propose a patch which tries to replicate this
2.4GHz specific behavior from nl80211_put_freq_params also in
ibss_mesh_setup_freq
Btw. thanks for pointing me towards specific test cases.
Kind regards,

I also see these fail if (and only if) I have this patch applied.
I'm going to drop this patch (again) for now, even if the situation is
now better I still don't want to knowingly break things there.
Please resend once that's all sorted out.

I pushed the relevant wpa_supplicant changes into hostap.git and all the
hwsim test cases pass now with the current snapshot when this
mac80211_hwsim patch is included.

Great, thanks. I've resurrected the patch in patchwork, so no need to
resend.
