tcp_bbr: TCP BBR changes for EDT pacing model

Two small patches for TCP BBR to follow up with Eric's recent work to change
the TCP and fq pacing machinery to an "earliest departure time" (EDT) model:

- The first patch adjusts the TCP BBR logic to work with the new
  "earliest departure time" (EDT) pacing model.

- The second patch adjusts the TCP BBR logic to centralize the setting
  of gain values, to simplify the code and prepare for future changes.

Centralize the code that sets gains used for computing cwnd and pacing
rate. This simplifies the code and makes it easier to change the state
machine or (in the future) dynamically change the gain values and
ensure that the correct gain values are always used.

Adjust TCP BBR for the new departure time pacing model in the recent
commit ab408b6d ("tcp: switch tcp and sch_fq to new earliest
departure time model").

With TSQ and pacing at lower layers, there are often several skbs
queued in the pacing layer, and thus there is less data "in the
network" than "in flight".

With departure time pacing at lower layers (e.g. fq or potential
future NICs), the data in the pacing layer now has a pre-scheduled
("baked-in") departure time that cannot be changed, even if the
congestion control algorithm decides to use a new pacing rate.

This means that there can be a non-trivial lag between when BBR makes
a pacing rate change and when the inter-skb pacing delays
change. After a pacing rate change, the number of packets in the
network can gradually evolve to be higher or lower, depending on
whether the sending rate is higher or lower than the delivery
rate. Thus ignoring this lag can cause significant overshoot, with the
flow ending up with too many or too few packets in the network.

This commit changes BBR to adapt its pacing rate based on the amount
of data in the network that it estimates has already been "baked in"
by previous departure time decisions. We estimate the number of our
packets that will be in the network at the earliest departure time
(EDT) for the next skb scheduled as:

   in_network_at_edt = inflight_at_edt - (EDT - now) * bw

If we're increasing the amount of data in the network ("in_network"),
then we want to know if the transmit of the EDT skb will push
in_network above the target, so our answer includes
bbr_tso_segs_goal() from the skb departing at EDT. If we're decreasing
in_network, then we want to know if in_network will sink too low just
before the EDT transmit, so our answer does not include the segments
from the skb departing at EDT.

Why do we treat pacing_gain > 1.0 case and pacing_gain < 1.0 case
differently? The in_network curve is a step function: in_network goes
up on transmits, and down on ACKs. To accurately predict when
in_network will go beyond our target value, this will happen on
different events, depending on whether we're concerned about
in_network potentially going too high or too low:

 o if pushing in_network up (pacing_gain > 1.0),
   then in_network goes above target upon a transmit event

 o if pushing in_network down (pacing_gain < 1.0),
   then in_network goes below target upon an ACK event

This commit changes the BBR state machine to use this estimated
"packets in network" value to make its decisions.

mlxsw: Add VxLAN support

This patchset adds support for VxLAN offload in the mlxsw driver.

With regards to the forwarding plane, VxLAN support is composed from two
main parts: Encapsulation and decapsulation.

In the device, NVE encapsulation (and VxLAN in particular) takes place
in the bridge. A packet can be encapsulated using VxLAN either because
it hit an FDB entry that forwards it to the router with the IP of the
remote VTEP or because it was flooded, in which case it is sent to a
list of remote VTEPs (in addition to local ports). In either case, the
VNI is derived from the filtering identifier (FID) the packet was
classified to at ingress and the underlay source IP is taken from a
device global configuration.

VxLAN decapsulation takes place in the underlay router, where packets
that hit a local route that corresponds to the source IP of the local
VTEP are decapsulated and injected to the bridge. The packets are
classified to a FID based on the VNI they came with.

The first six patches export the required APIs in the VxLAN and mlxsw
drivers in order to allow for the introduction of the NVE core in the
next two patches. The NVE core is designed to support a variety of NVE
encapsulations (e.g., VxLAN, NVGRE) and different ASICs, but currently
only VxLAN and Spectrum are supported. Spectrum-2 support will be added
in the future.

The last 10 patches add support for VxLAN decapsulation and
encapsulation and include the addition of the required switchdev APIs in
the VxLAN driver. These APIs allow capable drivers to get a notification
about the addition / deletion of FDB entries to / from the VxLAN's FDB.

Subsequent patchset will add selftests (generic and mlxsw-specific),
data plane learning, FDB extack and vetoing and support for VLAN-aware
bridges (one VNI per VxLAN device model).

v2:
* Implement netif_is_vxlan() using rtnl_link_ops->kind (Jakub & Stephen)
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

In the device, VxLAN encapsulation takes place in the FDB table where
certain {MAC, FID} entries are programmed with an underlay unicast IP.
MAC addresses that are not programmed in the FDB are flooded to the
relevant local ports and also to a list of underlay unicast IPs that are
programmed using the all zeros MAC address in the VxLAN driver.

One difference between the hardware and software data paths is the fact
that in the software data path there are two FDB lookups prior to the
encapsulation of the packet. First in the bridge's FDB table using {MAC,
VID} and another in the VxLAN's FDB table using {MAC, VNI}.

Therefore, when a new VxLAN FDB entry is notified, it is only programmed
to the device if there is a corresponding entry in the bridge's FDB
table. Similarly, when a new bridge FDB entry pointing to the VxLAN
device is notified, it is only programmed to the device if there is a
corresponding entry in the VxLAN's FDB table.

Note that the above scheme will result in a discrepancy between both
data paths if only one FDB table is populated in the software data path.
For example, if only the bridge's FDB is populated with an entry
pointing to a VxLAN device, then a packet hitting the entry will only be
flooded by the kernel to remote VTEPs whereas the device will also flood
the packets to other local ports member in the VLAN.

Enslavement of VxLAN devices to offloaded bridges was never forbidden by
mlxsw, but this patch makes sure the required configuration is performed
in order to allow VxLAN encapsulation and decapsulation to take place in
the device.

The patch handles both the case where a VxLAN device is enslaved to an
already offloaded bridge and the case where the first mlxsw port is
enslaved to a bridge that already has VxLAN device configured.

Invalid configurations are sanitized and an error string is returned via
extack.

Since encapsulation and decapsulation do not occur when the VxLAN device
is down, the driver makes sure to enable / disable these functionalities
based on NETDEV_PRE_UP and NETDEV_DOWN events.

Note that NETDEV_PRE_UP is used in favor of NETDEV_UP, as the former
allows to veto the operation, if necessary.

This changes with VxLAN encapsulation.

Devices capable of performing VxLAN encapsulation usually have only one
FDB table, unlike the software data path which has two - one in the
bridge driver and another in the VxLAN driver.

Therefore, bridge FDB entries pointing to a VxLAN device are only
offloaded if there is a corresponding entry in the VxLAN FDB.

Allow clearing the offload indication in case the corresponding entry
