dsa: Remove phydev parameter from disable_port call

2019-02-25T06:30:34Z

No current DSA driver makes use of the phydev parameter passed to the disable_port call. Remove it. Signed-off-by: Andrew Lunn Signed-off-by: David S. Miller

net: dsa: b53: Do not program CPU port's PVID

2019-02-16T04:37:54Z

The CPU port is special and does not need to obey VLAN restrictions as far as untagged traffic goes, also, having the CPU port be part of a particular PVID is against the idea of keeping it tagged in all VLANs.

net: dsa: b53: Properly account for VLAN filtering

2019-02-16T04:37:54Z

VLAN filtering can be built into the kernel, and also dynamically turned on/off through the bridge master device. Allow re-configuring the switch appropriately to account for that by deciding whether VLAN table (v_table) misses should lead to a drop or forward.

net: dsa: b53: Fix default VLAN ID

2019-02-16T04:37:54Z

We were not consistent in how the default VID of a given port was defined, b53_br_leave() would make sure the VLAN ID would be either 0/1 depending on the switch generation, but b53_configure_vlan(), which is the default configuration would unconditionally set it to 1. The correct value is 1 for 5325/5365 series and 0 otherwise. To avoid repeating that mistake ever again, introduce a helper function: b53_default_pvid() to factor that out.

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

2018-10-05T04:52:49Z

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.

net: dsa: b53: Also include SGMII for mac_config and mac_link_state

2018-09-22T03:01:19Z

In both 802.3z and SGMII modes we need to configure the MAC accordingly to flip between Fiber and SGMII modes, and we need to read the MAC status from the SGMII in-band control word.

net: dsa: b53: Add SerDes support

2018-09-06T14:48:34Z

Add support for the Northstar Plus SerDes which is accessed through a special page of the switch. Since this is something that most people probably will not want to use, make it a configurable option with a default on ARCH_BCM_NSP where it is the most useful currently. The SerDes supports both SGMII and 1000baseX modes for both lanes, and 2500baseX for one of the lanes, and is internally looking like a seemingly standard MII PHY, except for the few bits that got repurposed.

net: dsa: b53: Add PHYLINK support

2018-09-06T14:48:34Z

Add support for PHYLINK, things are reasonably straight forward since we do not yet support SerDes interfaces, that leaves us with just MLO_AN_PHY and MLO_AN_FIXED to deal with. Signed-off-by: Florian Fainelli Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller
