Subject: [PATCH] mt76: mt7915: send EAPOL frames at lowest rate
Git-commit: 68232efffe4e5ecac28597ade3a92fd9ad9322d4
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.
