I agree with you only partially.
Today, I do not see any driver advertising SW_CRYPTO_CONTROL other
than
ath10k. There could be some driver which would want to advertise
SW_CRYPTO_CONTROL and do not support the software encryption for VLAN
devices. In that case, hard-coding doesn't seem to solve the problem
completely right? No?
Well, my point is that such a hypothetical driver is completely
irrelevant because it doesn't make any sense to have this behaviour -
it would mean it cannot support AP_VLAN with encryption, so it might as
well not support AP_VLAN at all.
Or you meant to say that driver should advertise the support for
AP_VLANs only if it can support encryption on AP_VLAN devices?
Right.
If this
the case, then I could see some code in ieee80211_register_hw which
says
this,
/* if low-level driver supports AP, we also support VLAN */
if (local->hw.wiphy->interface_modes &
BIT(NL80211_IFTYPE_AP)) {
hw->wiphy->interface_modes |=
BIT(NL80211_IFTYPE_AP_VLAN);
hw->wiphy->software_iftypes |=
BIT(NL80211_IFTYPE_AP_VLAN);
}
Yes, but if such a driver comes along we can change this.
It makes sense, I will send out the change by hard-coding only for
AP-VLAN interface.
