net: dsa: b53: Fix for brcm tag issue in Cygnus SoC

2018-06-11T20:43:19+00:00

[ Upstream commit 5040cc990cbac98733df4d58fdeac5bbdab15b49 ] In the Broadcom Cygnus SoC, the brcm tag needs to be inserted in between the mac address and the ether type (should use 'DSA_PROTO_TAG_BRCM') for the packets sent to the internal b53 switch. Since the Cygnus was added with the BCM58XX device id and the BCM58XX uses 'DSA_PROTO_TAG_BRCM_PREPEND', the data path is broken, due to the incorrect brcm tag location. Add a new b53 device id (BCM583XX) for Cygnus family to fix the issue. Add the new device id to the BCM58XX family as Cygnus is similar to the BCM58XX in most other functionalities.

dsa: Pass the port to get_sset_count()

2018-03-04T18:34:18+00:00

By passing the port, we allow different ports to have different statistics. This is useful since some ports have SERDES interfaces with their own statistic counters. Signed-off-by: Andrew Lunn Tested-by: Florian Fainelli Reviewed-by: Vivien Didelot Signed-off-by: David S. Miller

net: dsa: remove trans argument from vlan ops

2017-12-03T02:18:55+00:00

The DSA switch VLAN ops pass the switchdev_trans structure down to the drivers, but no one is using them and they aren't supposed to anyway. Remove the trans argument from VLAN prepare and add operations. At the same time, fix the following checkpatch warning: WARNING: line over 80 characters #74: FILE: drivers/net/dsa/dsa_loop.c:177: + const struct switchdev_obj_port_vlan *vlan) Signed-off-by: Vivien Didelot Signed-off-by: David S.

net: dsa: bcm_sf2: Utilize b53_get_tag_protocol()

2017-11-30T18:00:04+00:00

Utilize the much more capable b53_get_tag_protocol() which takes care of all Broadcom switches specifics to resolve which port can have Broadcom tags enabled or not. Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

net: dsa: b53: Export b53_configure_vlan()

2017-10-29T03:13:30+00:00

bcm_sf2 and b53 replicate the same operations: clear all VLANs and set their ports to the default VLAN tag (1 for these devices) so export the b53 function doing just that. Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

net: dsa: bcm_sf2: Utilize b53_{enable, disable}_port

2017-09-19T23:08:54+00:00

Export b53_{enable,disable}_port and use these two functions in bcm_sf2_port_setup and bcm_sf2_port_disable. The generic functions cannot be used without wrapping because we need to manage additional switch integration details (PHY, Broadcom tag etc.).
