mlxsw: Add support for new port types and speeds for Spectrum-2
Shalom says:
This patchset adds support for new port types and speeds for Spectrum-2.
Patch #1 + #2 removes an unsupported PTYS field and a duplicate link
mode entry.
Patch #3 queries port's connector type from firmware instead of deriving
it from port admin state.
Patch #4 renames functions which relate to port type-speed to be
Spectrum-1 specific.
Patch #5 defines port type-speed operations and applies it for
Spectrum-1.
Patch #6 + #7 are small renaming and cosmetic changes.
Patch #8 adds new port type-speed fields for PTYS register. These new
fields extend the existing ones in order to support more types and
speeds.
Patch #9 adds Spectrum-2 support for port type-speed operations.
Patch #10 adds Spectrum-2 new port types and speeds.
For Spectrum-2, the user must configure all the types per speed if he /
she wants a specific speed to be advertised. For example, if the user
wants to advertise 100Gbps 4-lanes speed, the following ethtool bits
should be advertised:
Supported ethtool bits for 100Gbps 4-lanes:

In Virtual Ethernet Port Aggregator (VEPA) mode, the packet skips
the system internal virtual switch and forwards to external network
switch. In Mellanox HCA case, the virtual switch is the HCA's Eswitch.
To support this, an new FDB flow table are created with level 0 and
linked to the existing FDB flow table in legacy mode. By default,
VEPA is turned off and this FDB flow table is empty. When VEPA is
turned on, two rules are created. One rule to forward on uplink vport
traffic to the legacy FDB. The other rule forward all other traffic
to uplink vport.
Other design alternatives were not chosen as explained below:
1. Create a forward rule in ACL flow table (most efficient design).
This approach is the not chosen because firmware does not support
forward rule to uplink vport (0xffff) for ACL flow table.
2. Add additional source port criteria in all the FDB rules to make the
FDB rules to be received rules only. This approach is not chosen because
it is not efficient as there can many rules in the FDB and VEPA mode
cannot be controlled per vport.
3. Add a highest prioirty flow group in the existing legacy FDB Flow
Table instead of a new flow table. This approoach does not work because the
new flow group has the same match criteria as the promiscuous flow group
and mlx5_add_flow_rules does not allow specifying flow group.

net/mlx5e: Fix GRE key by controlling port tunnel entropy calculation
Flow entropy is calculated on the inner packet headers and used for
flow distribution in processing, routing etc. For GRE-type
encapsulations the entropy value is placed in the eight LSB of the key
field in the GRE header as defined in NVGRE RFC 7637. For UDP based
encapsulations the entropy value is placed in the source port of the
UDP header.
The hardware may support entropy calculation specifically for GRE and
for all tunneling protocols. With commit
df2ef3bff193 ("net/mlx5e: Add
GRE protocol offloading") GRE is offloaded, but the hardware is
configured by default to calculate flow entropy so packets transmitted
on the wire have a wrong key. To support UDP based tunnels (i.e VXLAN),
GRE (i.e. no flow entropy) and NVGRE (i.e. with flow entropy) the
hardware behaviour must be controlled by the driver.
Ensure port entropy calculation is enabled for offloaded VXLAN tunnels
and disable port entropy calculation in the presence of offloaded GRE
tunnels by monitoring the presence of entropy enabling tunnels (i.e
VXLAN) and entropy disabing tunnels (i.e GRE).

====================
net: dsa: VLAN devices w/ filtering
This patch series supports having VLAN devices on top of DSA/switch
ports while the switch has VLAN filtering globally turned on (as is the
case with Broadcom switches). Whether the switch does global or per-port
VLAN filtering, having VLAN entries for these VLAN devices is
beneficial.
We take care of a few possibly problematic cases:
- adding a VLAN device while there is an existing VLAN entry created by
a VLAN aware bridge. The entire bridge's VLAN database and not just
the specific bridge port is being checked to be safe and conserative
- adding a bridge VLAN entry when there is an existing VLAN device
created is also not possible because that would lead to the bridge
being able to manipulate the VLAN device's VID/attributes under its feet
- enslaving a VLAN device into a VLAN aware bridge since that duplicates
functionality already offered by the VLAN aware bridge
Here are the different test cases that were run to exercise this:
ip addr flush dev gphy
ip link add dev br0 type bridge
echo 1 > /sys/class/net/br0/bridge/vlan_filtering
ip link set dev gphy master br0
udhcpc -i br0

In order to properly support VLAN filtering being enabled/disabled on a

to support the ndo_vlan_rx_{add,kill}_vid callbacks in order to make
sure the non-bridge ports can continue receiving VLAN tags, even when
the switch is globally configured to do ingress/egress VID checking.
Since we can call dsa_port_vlan_{add,del} with a bridge_dev pointer
NULL, we now need to check that in these two functions.
We specifically deal with two possibly problematic cases:
- creating a bridge VLAN entry while there is an existing VLAN device
claiming that same VID

with that VID

====================
mlxsw: Support for shared buffers in Spectrum-2
Petr says:
Spectrum-2 will be configured with a different set of pools than
Spectrum-1, their sizes will be larger, and the individual quotas will
be different as well. It is therefore necessary to make the shared
buffer module aware of this dependence on chip type, and adjust the
individual tables.
In patch #1, introduce a structure for keeping per-chip immutable and
default values.
In patch #2, structures for keeping current values of SBPM and SBPR
(pool configuration and port-pool quota) are allocated dynamically to
support varying pool counts.
In patches #3 to #7, uses of individual shared buffer configuration
tables are migrated from global definitions to fields in struct
mlxsw_sp_sb_vals, which was introduced above.
Up until this point, the actual configuration is still the one suitable
for Spectrum-1. In patch #8 Spectrum-2 configuration is added.
In patch #9, port headroom configuration is changed to take into account
current recommended value for a 100-Gbps port, and the split factor.
In patch #10, requests for overlarge headroom are rejected. This avoids
potential chip freeze should such overlarge requests be made.

8fce33317023 introduced the concept of NAPI per-channel and
independent cleaning of TX path.
This is currently breaking performance in some cases. The scenario
happens when all packets are being received in Queue 0 but the TX is
performed in Queue != 0.
Fix this by using different NAPI instances per each TX and RX queue, as
suggested by Florian.

net: Get rid of switchdev_port_attr_get()
This patch series splits the removal of the switchdev_ops that was
proposed a few times before and first tackles the easy part which is the
removal of the single call to switchdev_port_attr_get() within the
bridge code.
As suggestd by Ido, this patch series adds a
SWITCHDEV_ATTR_ID_PORT_PRE_BRIDGE_FLAGS which is used in the same
context as the caller of switchdev_port_attr_set(), so not deferred, and
then the operation is carried out in deferred context with setting a
support bridge port flag.
Follow-up patches will do the switchdev_ops removal after introducing
the proper helpers for the switchdev blocking notifier to work across
stacked devices (unlike the previous submissions).
David this does depend on Russell's "[PATCH net-next v5 0/3] net: dsa:
mv88e6xxx: fix IPv6".
Changes in v3:
- rebased against net-next/master after Russell's IPv6 changes to DSA
- ignore prepare/commit phase for PRE_BRIDGE_FLAGS since we don't
want to trigger the WARN() in net/switchdev/switchdev.c in the commit
phase
Changes in v2:
- differentiate callers not supporting switchdev_port_attr_set() from
the driver not being able to support specific bridge flags
- pass "mask" instead of "flags" for the PRE_BRIDGE_FLAGS check
- skip prepare phase for PRE_BRIDGE_FLAGS
- corrected documentation a bit more
