WMM AC: Missing IEs

[Felix Åkerlund]

Hi,

I'm using wpa_supplicant v2.6 for wired EAP-TLS. It works just fine, but
whenever I start up wpa_supplicant on my device, I see the following error:
"WMM AC: Missing IEs".

While looking around in the code to figure out what's causing it, I get the
impression that this should perhaps not be treated as an error?
https://w1.fi/cgit/hostap/tree/wpa_supplicant/wmm_ac.c?h=hostap_2_6

The missing Information Elements are described as optional in the
wpa_event_data::assoc_info Struct Reference here:
https://w1.fi/wpa_supplicant/devel/structwpa__event__data_1_1assoc__info.html

If the IEs are missing, perhaps a debug message should be printed rather than an
error, or maybe wmm_ac_init() should not be called in the first place.

Regards,
Felix
