OpenWrt 21.02.0 - First Stable Release

Is there anyone 802.11r (FT) works in 21.02 release?
I think 802.11r function is broken in 21.02.

My devices:

  • QCA9880 / ath10k-ct
  • MT7613E / mt76
  • MT7615E / mt76

Clients:

  • iPhone 6
  • iPohne XR

FT never works.
At handshake timing, log says:

daemon.err hostapd: nl80211: kernel reports: key addition failed.

Both [FT over DS] and [FT over Air] are same.
