Subject: [PATCH] mt76: mt7921: send EAPOL frames at lowest rate
Git-commit: 7780ba75c5da07cf55a88886691e94f3c71e82ad
Patch-mainline: v5.16-rc1
References: bsc#1209980
The firmware rate control may choose the high rate for EAPOL frames,
so checking IEEE80211_TX_CTL_USE_MINRATE to use the lowest TX rate.
