net: dsa: loop: Set correct number of ports

2020-08-04T01:19:23+00:00

We only support DSA_LOOP_NUM_PORTS in the switch, do not tell the DSA core to allocate up to DSA_MAX_PORTS which is nearly the double (6 vs. 11). Signed-off-by: Florian Fainelli Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: dsa: loop: Wire-up MTU callbacks

2020-08-04T01:19:23+00:00

For now we simply store the port MTU into a per-port member. Signed-off-by: Florian Fainelli Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: dsa: loop: Move data structures to header

2020-08-04T01:19:23+00:00

In preparation for adding support for a mockup data path, move the driver data structures to include/linux/dsa/loop.h such that we can share them between net/dsa/ and drivers/net/dsa/ later on. Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

net: dsa: loop: Support 4K VLANs

2020-08-04T01:19:22+00:00

Allocate a 4K array of VLANs instead of limiting ourselves to just 5 which is arbitrary. Signed-off-by: Florian Fainelli Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: dsa: loop: PVID should be per-port

2020-08-04T01:19:22+00:00

The PVID should be per-port, this is a preliminary change to support a 802.1Q data path in the driver. Signed-off-by: Florian Fainelli Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: dsa: loop: Print when registration is successful

2020-07-08T17:14:00+00:00

We have a number of error conditions that can lead to the driver not probing successfully, move the print when we are sure dsa_register_switch() has suceeded. This avoids repeated prints in case of probe deferral for instance. Signed-off-by: Florian Fainelli Reviewed-by: Andrew Lunn Reviewed-by: Vivien Didelot Signed-off-by: David S. Miller

net: dsa: loop: Add module soft dependency

2020-05-10T18:24:20+00:00

There is a soft dependency against dsa_loop_bdinfo.ko which sets up the MDIO device registration, since there are no symbols referenced by dsa_loop.ko, there is no automatic loading of dsa_loop_bdinfo.ko which is needed.

net: dsa: Get information about stacked DSA protocol

2020-01-09T00:01:13+00:00

It is possible to stack multiple DSA switches in a way that they are not part of the tree (disjoint) but the DSA master of a switch is a DSA slave of another. When that happens switch drivers may have to know this is the case so as to determine whether their tagging protocol has a remove chance of working. This is useful for specific switch drivers such as b53 where devices have been known to be stacked in the wild without the Broadcom tag protocol supporting that feature. This allows b53 to continue supporting those devices by forcing the disabling of Broadcom tags on the outermost switches if necessary. The get_tag_protocol() function is therefore updated to gain an additional enum dsa_tag_protocol argument which denotes the current tagging protocol used by the DSA master we are attached to, else DSA_TAG_PROTO_NONE for the top of the dsa_switch_tree.

net: dsa: remove dsa_switch_alloc helper

2019-10-22T19:37:07+00:00

Now that ports are dynamically listed in the fabric, there is no need to provide a special helper to allocate the dsa_switch structure. This will give more flexibility to drivers to embed this structure as they wish in their private structure. Signed-off-by: Vivien Didelot Reviewed-by: Florian Fainelli Signed-off-by: Jakub Kicinski
