net: dsa: add support switches global DSCP priority mapping

2024-05-08T09:35:10+00:00

Some switches like Microchip KSZ variants do not support per port DSCP
priority configuration. Instead there is a global DSCP mapping table.

To handle it, we will accept set/del request to any of user ports to
make global configuration and update dcb app entries for all other
ports.

net: dsa: add support for DCB get/set apptrust configuration

2024-05-08T09:35:09+00:00

Add DCB support to get/set trust configuration for different packet
priority information sources. Some switch allow to chose different
source of packet priority classification. For example on KSZ switches it
is possible to configure VLAN PCP and/or DSCP sources.

net: dsa: Remove adjust_link paths

2024-05-02T02:06:32+00:00

Now that we no longer any drivers using PHYLIB's adjust_link callback,
remove all paths that made use of adjust_link as well as the associated
functions.

devlink: extend devlink_param *set pointer

2024-04-22T20:05:19+00:00

Extend devlink_param *set function pointer to take extack as a param.
Sometimes it is needed to pass information to the end user from set
function. It is more proper to use for that netlink instead of passing
message to dmesg.

net: dsa: allow DSA switch drivers to provide their own phylink mac ops

2024-04-12T03:01:14+00:00

Rather than having a shim for each and every phylink MAC operation,
allow DSA switch drivers to provide their own ops structure. When a
DSA driver provides the phylink MAC operations, the shimmed ops must
not be provided, so fail an attempt to register a switch with both
the phylink_mac_ops in struct dsa_switch and the phylink_mac_*
operations populated in dsa_switch_ops populated.

ethtool: replace struct ethtool_eee with a new struct ethtool_keee on kernel side

2024-01-31T12:30:47+00:00

In order to pass EEE link modes beyond bit 32 to userspace we have to
complement the 32 bit bitmaps in struct ethtool_eee with linkmode
bitmaps. Therefore, similar to ethtool_link_settings and
ethtool_link_ksettings, add a struct ethtool_keee. In a first step
it's an identical copy of ethtool_eee. This patch simply does a
s/ethtool_eee/ethtool_keee/g for all users.
No functional change intended.

net: dsa: notify drivers of MAC address changes on user ports

2023-10-03T11:51:02+00:00

In some cases, drivers may need to veto the changing of a MAC address on
a user port. Such is the case with KSZ9477 when it offloads a HSR device,
because it programs the MAC address of multiple ports to a shared
hardware register. Those ports need to have equal MAC addresses for the
lifetime of the HSR offload.
