In symmetric routing, the only two members in the VLAN corresponding to
the L3 VNI are the router port and the VXLAN tunnel.
In case the VXLAN device is already enslaved to the bridge and only
later the VLAN interface is configured, the tunnel will not be
offloaded.
The reason for this is that when the router interface (RIF)
corresponding to the VLAN interface is configured, it calls the core
fid_get() API which does not check if NVE should be enabled on the FID.
Instead, call into the bridge code which will check if NVE should be
enabled on the FID.
This effectively means that the same code path is used to retrieve a FID
when either a local port or a router port joins the FID.

In the past we had multiple instances where RIFs were not properly
deleted.
One of the reasons for leaking a RIF was that at the time when IP
addresses were flushed from the respective netdev (prompting the
destruction of the RIF), the netdev was no longer a mlxsw upper. This
caused the inet{,6}addr notification blocks to ignore the NETDEV_DOWN
event and leak the RIF.
Instead of checking whether the netdev is our upper when an IP address
is removed, we can instead check if the netdev has a RIF configured.
To look up a RIF we need to access mlxsw private data, so the patch
stores the notification blocks inside a mlxsw struct. This then allows
us to use container_of() and extract the required private data.

Commit b3529af6bb ("spectrum: Reference count VLAN entries") started
reference counting port-VLAN entries in a similar fashion to the 8021q
driver.
However, this is not actually needed and only complicates things.
Instead, the driver should forbid the creation of a VLAN on a port if
this VLAN already exists. This would also solve the issue fixed by the
mentioned commit.
Therefore, remove the get()/put() API and use create()/destroy()
instead.
One place that needs special attention is VLAN addition in a VLAN-aware
bridge via switchdev operations. In case the VLAN flags (e.g., 'pvid')
are toggled, then the VLAN entry already exists. To prevent the driver
from wrongly returning EEXIST, the driver is changed to check in the
prepare phase whether the entry already exists and only returns an error
in case it is not associated with the correct bridge port.

Currently, when a RIF is constructed on top of a FID, the RIF increments
the FID's reference count and the RIF is destroyed when the FID's
reference count drops to 1. This effectively means that when no local
ports are member in the FID, the FID is destroyed regardless if the
router port is a member in the FID or not.
The above can lead to the unexpected behavior in which routes using a
VLAN interface as their nexthop device are no longer offloaded after the
last local port leaves the corresponding VLAN (FID).
Example:
# ip -4 route show dev br0.10
192.0.2.0/24 proto kernel scope link src 192.0.2.1 offload
# bridge vlan del vid 10 dev swp3
# ip -4 route show dev br0.10
192.0.2.0/24 proto kernel scope link src 192.0.2.1
After the patch, the route is offloaded before and after the VLAN is
removed from local port 'swp3', as the RIF corresponding to 'br0.10'
continues to exists.
In order to remove RIFs' reliance on the underlying FID's reference
count, we need to add a reference count to sub-port RIFs, which are RIFs
that correspond to physical ports and their uppers (e.g., LAG devices).
In this case, each {Port, VID} ('struct mlxsw_sp_port_vlan') needs to
hold a reference on the RIF. For example:
bond0.10
|
bond0
|
+-------+
| |
swp1 swp2
Both {Port 1, VID 10} and {Port 2, VID 10} will hold a reference on the
RIF corresponding to 'bond0.10'. When the last reference is dropped, the
RIF will be destroyed.

mlxsw ports (or their upper) as slaves. This patch extends mlxsw to also

The patch is similar in nature to mentioned commit, but there is one
major difference. With VLAN-aware bridges, the VxLAN device's VNI is
mapped to the VLAN that is configured as PVID and egress untagged on the
bridge port.
Therefore, the driver is extended to listen to VLAN configuration on
VxLAN devices of interest and enable / disable NVE encapsulation on the
corresponding 802.1Q FIDs.
To prevent ambiguity, the driver makes sure that a given VLAN is not
configured as PVID and egress untagged on multiple VxLAN devices. This
sanitization takes place both when a port is enslaved to a bridge with
existing VxLAN devices and when a VLAN is added to / removed from a
VxLAN device of interest.

on the associated FIDs (filtering identifier). If the reference count of
a FID is 1 and it has a RIF (router interface), then this RIF is
destroyed.
However, if no port is member in the VLAN for which a RIF exists, then
the RIF will continue to exist after the removal of the bridge. To

# ip address add 192.0.2.0/24 dev br0.10

point rewrite on egress.
- Default priority (selector 1, PID 0) to configure priority for the
DSCP code points that don't have one assigned by the DSCP selector. In
future this could also be used for assigning default port priority
when a packet arrives without DSCP tagging.
Besides setting up the maps themselves, also configure port trust level
and rewrite bits.
Port trust level determines whether, for a packet arriving through a
certain port, the priority should be determined based on PCP or DSCP
header fields. So far, mlxsw kept the device default of trust-PCP. Now,
as soon as the first DSCP APP TLV is configured, switch to trust-DSCP.
Only when all DSCP APP TLVs are removed, switch back to trust-PCP again.
Note that the default priority APP TLV doesn't impact the trust level
configuration.
Rewrite bits determine whether DSCP and PCP fields of egressing packets
should be updated according to switch priority. When port trust is
switched to DSCP, enable rewrite of DSCP field.
