Is it even correct? Probably not, this is kind of left over from before adding the sfp phandle, but if I do remove it, and I can see the DSA slave network device fail to initialize, likely because we destroy the PHYLINK instance. AFAIR, when we talked about this with Russell, I did not see why we had to comment out the following: diff --git a/net/dsa/slave.c b/net/dsa/slave.c index 962c4fd338ba..f3ae16dbf8d8 100644 --- a/net/dsa/slave.c +++ b/net/dsa/slave.c @@ -1227,7 +1227,7 @@ static int dsa_slave_phy_setup(struct net_device *slave_dev) netdev_err(slave_dev, "failed to connect to port %d: %d\n", dp->index, ret); - phylink_destroy(dp->pl); + //phylink_destroy(dp->pl); return ret; } } maybe you know? -- Florian
