mv88e6060: disable hardware level MAC learning

2018-12-21T13:11:38+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.

net: dsa: bcm_sf2: Fix unbind ordering

2018-10-18T07:13:23+00:00

[ Upstream commit bf3b452b7af787b8bf27de6490dc4eedf6f97599 ]

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: bcm_sf2: Call setup during switch resume

2018-10-18T07:13:22+00:00

[ Upstream commit 54baca096386d862d19c10f58f34bf787c6b3cbe ]

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: qca8k: Allow overwriting CPU port setting

2018-08-03T05:55:27+00:00

commit 9bb2289f90e671bdb78e306974187424ac19ff8e upstream.

Implement adjust_link function that allows to overwrite default CPU port
setting using fixed-link device tree subnode.

net: dsa: qca8k: Enable RXMAC when bringing up a port

commit eee1fe64765c562d8bcaf95e5631a8ea2f760f34 upstream.

When a port is brought up/down do not enable/disable only the TXMAC
but the RXMAC as well. This is essential for the CPU port to work.

net: dsa: qca8k: Force CPU port to its highest bandwidth

commit 79a4ed4f0f93fc65e48a0fc5247ffa5645f7b0cc upstream.

By default autonegotiation is enabled to configure MAC on all ports.
For the CPU port autonegotiation can not be used so we need to set
some sensible defaults manually.

This patch forces the default setting of the CPU port to 1000Mbps/full
duplex which is the chip maximum capability.

Also correct size of the bit field used to configure link speed.

net: dsa: b53: Include IMP/CPU port in dumb forwarding mode

[ Upstream commit a424f0de61638cbb5047e0a888c54da9cf471f90 ]

Since Broadcom tags are not enabled in b53 (DSA_PROTO_TAG_NONE), we need
to make sure that the IMP/CPU port is included in the forwarding
decision.

Without this change, switching between non-management ports would work,
but not between management ports and non-management ports thus breaking
the default state in which DSA switch are brought up.
