Hello,
This is scenario:
1) insmod cfg80211.ko
2) iw reg set FR
3) modprobe ath10k_pci (default US will be registered)
4) intersection here - is it as designed? Country "98"
5) after that no way to setup new country using iw reg set (lock),
always fail in such code:
__reg_process_hint_user(...)
if ((lr->initiator == NL80211_REGDOM_SET_BY_CORE ||
lr->initiator == NL80211_REGDOM_SET_BY_DRIVER ||
lr->initiator == NL80211_REGDOM_SET_BY_USER) &&
regdom_changes(lr->alpha2))
return REG_REQ_IGNORE;
Last request still have "US" - shouldn't be "98" like we set in intersection?
Such patch setup same alpha2 for last request (also in case of we will
change this in intersection)
@Luis could you check this patch, I am not sure this is best fix for that?
