+Subject: [PATCH 134/199] mtk: mt76: mt7996: do software link addr translation
+ for EAPOL
+
+Previously, we do HW link address translation for EAPOL addr1 and addr2,
+but SW link address translation for EAPOL addr3 due to incompatibility
+between HW converting rules and 802.11 EAPOL frames.
+
+This patch adds support for doing pure SW link address translation for
+EAPOL, to get rid of ambiguity and could also help on debugging EAPOL
+timeout issues.
+
+Note that dma_sync_single_for_cpu/dma_sync_single_for_device is
+necessary to sync the changes of address to DMA.
+
+Assign EAPOL's SA/DA to MLD address.
