When we use the bindings defined in Documentation/devicetree/bindings/mux to define mdio mux in producer and consumer terms, it results in two devices. one is mux producer and other is mux consumer. Add the bindings needed for Mdio mux consumer devices. Signed-off-by: Pankaj Bansal <pankaj.bansal@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Current fib_multipath_hash_policy can make hash based on the L3 or L4. But it only work on the outer IP. So a specific tunnel always has the same hash value. But a specific tunnel may contain so many inner connections. This patch provide a generic multipath_hash in floi_common. It can make a user-define hash which can mix with L3 or L4 hash.

Florian Fainelli says: ==================== net: Remove switchdev_ops This patch series completes the removal of the switchdev_ops by converting switchdev_port_attr_set() to use either the blocking (process) or non-blocking (atomic) notifier since we typically need to deal with both depending on where in the bridge code we get called from. This was tested with the forwarding selftests and DSA hardware. Ido, hopefully this captures your comments done on v1, if not, can you illustrate with some pseudo-code what you had in mind if that's okay? Changes in v3: - added Reviewed-by tags from Ido where relevant - added missing notifier_to_errno() in net/bridge/br_switchdev.c when calling the atomic notifier for PRE_BRIDGE_FLAGS - kept mlxsw_sp_switchdev_init() in mlxsw/ Changes in v2: - do not check for SWITCHDEV_F_DEFER when calling the blocking notifier and instead directly call the atomic notifier from the single location where this is required ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Drop switchdev_ops.switchdev_port_attr_set. Drop the uses of this field from all clients, which were migrated to use switchdev notification in the previous patches. Add a new function switchdev_port_attr_notify() that sends the switchdev notifications SWITCHDEV_PORT_ATTR_SET and calls the blocking (process) notifier chain. We have one odd case within net/bridge/br_switchdev.c with the SWITCHDEV_ATTR_ID_PORT_PRE_BRIDGE_FLAGS attribute identifier that requires executing from atomic context, we deal with that one specifically. Drop __switchdev_port_attr_set() and update switchdev_port_attr_set() likewise.

Roopa Prabhu says: ==================== vxlan: create and changelink extack support This series adds extack support to changelink paths. In the process re-factors flag sets to a separate helper. Also adds some changelink testcases to rtnetlink.sh (This series was initially part of another series that tried to support changelink for more attributes. But after some feedback from sabrina, i have dropped the 'support changelink for more attributes' part because some of them cannot be supported today or may require additional use-case handling code. These can be done separately as and when we see the need for it.) ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Jakub Kicinski says: ==================== devlink: make ethtool compat reliable This is a follow up to the series which added device flash updates via devlink. I went with the approach of adding a new NDO in the end. It seems to end up looking cleaner. First patch removes the option to build devlink as a module. Users can still decide to not build it, but the module option ends up not being worth the maintenance cost. Next two patches add a NDO which can be used to ask the driver to return a devlink instance associated with a given netdev, instead of iterating over devlink ports. Drivers which implement this NDO must take into account the potential impact on the visibility of the devlink instance. With the new NDO in place we can remove NFP ethtool flash update code. Fifth patch makes sure we hold a reference to dev while callbacks are active. Last but not least the NULL-check of devlink->ops is moved to instance allocation time. Last but not least missing checks for devlink->ops are added. There is currently no driver registering devlink without ops, so can just fix this in -next. v2 (Michal): add netdev_to_devlink() in patch 3. v3 (Florian): - add missing checks for devlink->ops; - move locking/holding into devlink_compat_ functions. v4 (Jiri): - hold devlink_mutex around callbacks (patch 2); - require non-NULL ops (patch 6). ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Commit 76726ccb ("devlink: add flash update command") and commit 2d8dc5bb ("devlink: Add support for reload") access devlink ops without NULL-checking. There is, however, no driver which would pass in NULL ops, so let's just make that a requirement. Remove the now unnecessary NULL-checking.

Being able to build devlink as a module causes growing pains. First all drivers had to add a meta dependency to make sure they are not built in when devlink is built as a module.
