6.11-stable review patch. If anyone has any objections, please let me know.
------------------
From: Miri Korenblit <miriam.rachel.korenblit@xxxxxxxxx>
[ Upstream commit cbe84e9ad5e28ef083beff7f6edf2e623fac09e4 ]
iwl_mvm_send_ap_tx_power_constraint_cmd is a no-op if the link is not
active (we need to know the band etc.)
However, for the station case it will be called just before we set the
link to active (by calling iwl_mvm_link_changed with
the LINK_CONTEXT_MODIFY_ACTIVE bit set in the 'changed' flags and
active = true), so it will end up doing nothing.
Fix this by calling iwl_mvm_send_ap_tx_power_constraint_cmd before
iwl_mvm_link_changed.
Fixes: 6b82f4e119d1 ("wifi: iwlwifi: mvm: handle TPE advertised by AP")
