      net: mscc: ocelot: offload VLAN mangle action to VCAP IS1 · 70edfae1
      由 Vladimir Oltean 提交于 
      The VCAP_IS1_ACT_VID_REPLACE_ENA action, from the VCAP IS1 ingress TCAM,
changes the classified VLAN.

We are only exposing this ability for switch ports that are under VLAN
aware bridges. This is because in standalone ports mode and under a
bridge with vlan_filtering=0, the ocelot driver configures the switch to
operate as VLAN-unaware, so the classified VLAN is not derived from the
802.1Q header from the packet, but instead is always equal to the
port-based VLAN ID of the ingress port. We _can_ still change the
classified VLAN for packets when operating in this mode, but the end
result will most likely be a drop, since both the ingress and the egress
port need to be members of the modified VLAN. And even if we install the
new classified VLAN into the VLAN table of the switch, the result would
still not be as expected: we wouldn't see, on the output port, the
modified VLAN tag, but the original one, even though the classified VLAN
was indeed modified. This is because of how the hardware works: on
egress, what is pushed to the frame is a "port tag", which gives us the
following options:

- Tag all frames with port tag (derived from the classified VLAN)
- Tag all frames with port tag, except if the classified VLAN is 0 or
  equal to the native VLAN of the egress port
- No port tag

Needless to say, in VLAN-unaware mode we are disabling the port tag.
Otherwise, the existing VLAN tag would be ignored, and a second VLAN
tag (the port tag), holding the classified VLAN, would be pushed
(instead of replacing the existing 802.1Q tag). This is definitely not
what the user wanted when installing a "vlan modify" action.

So it is simply not worth bothering with VLAN modify rules under other
configurations except when the ports are fully VLAN-aware.

      enetc: Migrate to PHYLINK and PCS_LYNX · 71b77a7a
      由 Claudiu Manoil 提交于 
      This is a methodical transition of the driver from phylib
to phylink, following the guidelines from sfp-phylink.rst.
The MAC register configurations based on interface mode
were moved from the probing path to the mac_config() hook.
MAC enable and disable commands (enabling Rx and Tx paths
at MAC level) were also extracted and assigned to their
corresponding phylink hooks.
As part of the migration to phylink, the serdes configuration
from the driver was offloaded to the PCS_LYNX module,
introduced in commit 0da4c3d3 ("net: phy: add Lynx PCS module"),
the PCS_LYNX module being a mandatory component required to
make the enetc driver work with phylink.

      enetc: Clean up MAC and link configuration · 08f90fc9
      由 Claudiu Manoil 提交于 
      Decouple level MAC configuration based on phy interface type
from general port configuration.
Group together MAC and link configuration code.
Decouple external mdio bus creation from interface type
parsing.  No longer return an (unhandled) error code when
phy_node not found, use phy_node to indicate whether the
port has a phy or not.  No longer fall-through when serdes
configuration fails for the link modes that require
internal link configuration.
