This changes the 'uevent' attribute, before, it would look like this: cat /sys/class/net/gphy/uevent OF_NAME=port OF_FULLNAME=/rdb/switch_top@f0b00000/ethernet_switch@0/switch@0/port@0 OF_COMPATIBLE_N=0 OF_ALIAS_0=switch_port0 INTERFACE=gphy IFINDEX=3 # With that change it looks like this: # cat /sys/class/net/gphy/uevent DEVTYPE=dsa OF_NAME=port OF_FULLNAME=/rdb/switch_top@f0b00000/ethernet_switch@0/switch@0/port@0 OF_COMPATIBLE_N=0 OF_ALIAS_0=switch_port0 INTERFACE=gphy IFINDEX=3 VLAN does a similar thing: DEVTYPE=vlan INTERFACE=eth0.2 IFINDEX=14 > > Also, don't you think that this "dsa" device type might be conflicting > with eventually exposed DSA ports? Or will they all get the same type? Well, as of today these ports are not exposed, it is unclear to me whether they would be real network devices (with an actual struct device backing them), and we may want to dedicate a specific DEVTYPE like "dsa-pseudo-port" or something like that, specifically for these devices. Hope this clarifies the intent and usefulness of the patch. -- Florian -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
