From 5a59a58ec25d44f853c26bdbfda47d73b3067435 Mon Sep 17 00:00:00 2001 From: Alexander Sverdlin Date: Wed, 31 May 2023 16:38:26 +0200 Subject: [PATCH] net: dsa: lan9303: allow vid != 0 in port_fdb_{add|del} methods LAN9303 doesn't associate FDB (ALR) entries with VLANs, it has just one global Address Logic Resolution table [1]. Ignore VID in port_fdb_{add|del} methods, go on with the global table. This is the same semantics as hellcreek or RZ/N1 implement. Visible symptoms: LAN9303_MDIO 5b050000.ethernet-1:00: port 2 failed to delete 00:xx:xx:xx:xx:cf vid 1 from fdb: -2 LAN9303_MDIO 5b050000.ethernet-1:00: port 2 failed to add 00:xx:xx:xx:xx:cf vid 1 to fdb: -95 [1] https://ww1.microchip.com/downloads/en/DeviceDoc/00002308A.pdf Fixes: 0620427ea0d6 ("net: dsa: lan9303: Add fdb/mdb manipulation") Signed-off-by: Alexander Sverdlin Reviewed-by: Vladimir Oltean Link: https://lore.kernel.org/r/20230531143826.477267-1-alexander.sverdlin@siemens.com Signed-off-by: Jakub Kicinski --- drivers/net/dsa/lan9303-core.c | 4 ---- 1 file changed, 4 deletions(-) diff --git a/drivers/net/dsa/lan9303-core.c b/drivers/net/dsa/lan9303-core.c index cbe831875347..c0215a8770f4 100644 --- a/drivers/net/dsa/lan9303-core.c +++ b/drivers/net/dsa/lan9303-core.c @@ -1188,8 +1188,6 @@ static int lan9303_port_fdb_add(struct dsa_switch *ds, int port, struct lan9303 *chip = ds->priv; dev_dbg(chip->dev, "%s(%d, %pM, %d)\n", __func__, port, addr, vid); - if (vid) - return -EOPNOTSUPP; return lan9303_alr_add_port(chip, addr, port, false); } @@ -1201,8 +1199,6 @@ static int lan9303_port_fdb_del(struct dsa_switch *ds, int port, struct lan9303 *chip = ds->priv; dev_dbg(chip->dev, "%s(%d, %pM, %d)\n", __func__, port, addr, vid); - if (vid) - return -EOPNOTSUPP; lan9303_alr_del_port(chip, addr, port); return 0; -- 2.25.1
