mv88e6060: disable hardware level MAC learning

2018-12-21T13:15:20+00:00

[ Upstream commit a74515604a7b171f2702bdcbd1e231225fb456d0 ] Disable hardware level MAC learning because it breaks station roaming. When enabled it drops all frames that arrive from a MAC address that is on a different port at learning table. Signed-off-by: Anderson Luiz Alves Reviewed-by: Andrew Lunn Signed-off-by: David S.

net: dsa: mv88e6xxx: Fix clearing of stats counters

2018-11-23T07:17:06+00:00

[ Upstream commit a9049ff9214da68df1179a7d5e36b43479abc9b8 ] The mv88e6161 would sometime fail to probe with a timeout waiting for the switch to complete an operation. This operation is supposed to clear the statistics counters. However, due to a read/modify/write, without the needed mask, the operation actually carried out was more random, with invalid parameters, resulting in the switch not responding. We need to preserve the histogram mode bits, so apply a mask to keep them.

net: dsa: bcm_sf2: Call setup during switch resume

2018-10-11T22:19:54+00:00

There is no reason to open code what the switch setup function does, in fact, because we just issued a switch reset, we would make all the register get their default values, including for instance, having unused port be enabled again and wasting power and leading to an inappropriate switch core clock being selected.

net: dsa: bcm_sf2: Fix unbind ordering

2018-10-11T22:19:40+00:00

The order in which we release resources is unfortunately leading to bus errors while dismantling the port. This is because we set priv->wol_ports_mask to 0 to tell bcm_sf2_sw_suspend() that it is now permissible to clock gate the switch. Later on, when dsa_slave_destroy() comes in from dsa_unregister_switch() and calls dsa_switch_ops::port_disable, we perform the same dismantling again, and this time we hit registers that are clock gated. Make sure that dsa_unregister_switch() is the first thing that happens, which takes care of releasing all user visible resources, then proceed with clock gating hardware. We still need to set priv->wol_ports_mask to 0 to make sure that an enabled port properly gets disabled in case it was previously used as part of Wake-on-LAN.

net: dsa: b53: Keep CPU port as tagged in all VLANs

2018-10-05T04:52:49+00:00

Commit c499696e7901 ("net: dsa: b53: Stop using dev->cpu_port incorrectly") was a bit too trigger happy in removing the CPU port from the VLAN membership because we rely on DSA to program the CPU port VLAN, which it does, except it does not bother itself with tagged/untagged and just usese untagged. Having the CPU port "follow" the user ports tagged/untagged is not great and does not allow for properly differentiating, so keep the CPU port tagged in all VLANs.
