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: Fix for failure when irq is not defined in dt

2019-02-08T02:18:37Z

Fixes the issues with non BCM58XX chips in the b53 driver failing, when the irq is not specified in the device tree. Removed the check for BCM58XX in b53_srab_prepare_irq(), so the 'port->irq' will be set to '-EXIO' if the irq is not specified in the device tree.

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: Fix build with B53_SRAB enabled and B53_SERDES=m

2018-09-28T17:33:42Z

When B53_SERDES is a loadable module, a built-in srab driver still cannot reach it, so the previous fix is incomplete: b53_srab.c:(.text+0x3f4): undefined reference to `b53_serdes_init' drivers/net/dsa/b53/b53_srab.o:(.rodata+0xe64): undefined reference to `b53_serdes_link_state' drivers/net/dsa/b53/b53_srab.o:(.rodata+0xe74): undefined reference to `b53_serdes_link_set' drivers/net/dsa/b53/b53_srab.o:(.rodata+0xe88): undefined reference to `b53_serdes_an_restart' drivers/net/dsa/b53/b53_srab.o:(.rodata+0xea0): undefined reference to `b53_serdes_phylink_validate' drivers/net/dsa/b53/b53_srab.o:(.rodata+0xea4): undefined reference to `b53_serdes_config' Add a Kconfig dependency that forces srab to also be a module in this case, but allow it to be built-in when serdes is disabled or built-in.

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: Fix B53_SERDES_DIGITAL_CONTROL offset

2018-09-22T03:01:19Z

Maths went wrong, to get 0x20, we need to do 0x1e + (x) * 2, not 0x18, fix that offset so we access the correct registers. This would make us not access the correct SerDes Digital control words, status would be fine and so we would not be correctly flipping between Fiber and SGMII modes resulting in incorrect status words being pulled into the SerDes digital status register.
