When IVL is set, MAC[47:0] and CVID[11:0] will be used to read/write the address table. Since the function only fills in CVID and no FID, we need to set the IVL bit. The existing code does not set it. This is a fix for the issue I dropped here earlier: http://lists.infradead.org/pipermail/linux-mediatek/2021-June/025697.html With this patch, it is now possible to delete the 'self' fdb entry manually. However, wifi roaming still has the same issue, the entry does not get deleted automatically. Wifi roaming also needs a fix somewhere else to function correctly in combination with vlan.
