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 df2ef3bf ("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).

When using the device packet encapsulation offload, the device calculates an entropy value, representing the inner packet headers. The entropy field is placed inside the outer packet headers. For UDP-type encapsulations, the entropy is placed in the source port field of the UDP header. For GRE-type encapsulations, the entropy is placed in the 8 LSB of the key field in the GRE header. If the device does not recognize the encapsulation type, the entropy is not placed in the packet. Entropy setting can be controlled using PCMR register. if encapsulation offload is not used force_entropy_cap should be set to 0x0. Entropy setting is enabled/disabled using entropy_calc, and could be additionally enabled/disabled for GRE encapsulation by entropy_gre_calc. As a pre-step to automatically control the tunnel entropy, introduce the entropy fields in the PCMR register with no functional change. Signed-off-by:

Currently changing a PCMR field is done by setting the field in a zeroed buffer, zeroing other unrelated fields. Fix this behaviour by modifying only the required field after first reading the current register values, as a pre-step towards using more fields in PCMR register. Signed-off-by:

Florian Fainelli says: ==================== 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 vconfig add rgmii_1 100 ifconfig rgmii_1.100 192.168.100.10 ping -c 2 192.168.100.1 vconfig add br0 42 bridge vlan add vid 42 dev gphy bridge vlan add vid 42 dev br0 self ifconfig br0.42 192.168.42.2 ping -c 2 192.168.42.1 ip link del rgmii_1.100 vconfig add rgmii_1 100 ifconfig rgmii_1.100 192.168.100.10 ping -c 2 192.168.100.1 echo 0 > /sys/class/net/br0/bridge/vlan_filtering ping -c 2 192.168.100.1 ip link del rgmii_1.100 echo 1 > /sys/class/net/br0/bridge/vlan_filtering vconfig add rgmii_1 100 brctl addif br0 rgmii_1 bridge vlan add vid 100 dev rgmii_1 vconfig rem rgmii_1.100 bridge vlan add vid 100 dev rgmii_1 vconfig add rgmii_1 100 bridge vlan del vid 100 dev rgmii_1 vconfig add rgmii_1 100 brctl addif br0 rgmii_1.100 ==================== Signed-off-by:David S.

In order to properly support VLAN filtering being enabled/disabled on a bridge, while having other ports being non bridge port members, we need 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 - creating a VLAN device while there is an existing bridge VLAN entry with that VID Those are both resolved with returning -EBUSY back to user-space.

VLAN devices on top of a DSA network device which is already part of a bridge and with said bridge being VLAN aware should not be allowed to be enslaved into that bridge. For one, this duplicates functionality offered by the VLAN aware bridge which supports tagged and untagged VLAN frames processing and it would make things needlessly complex to e.g.: propagate FDB/MDB accordingly.

Ido Schimmel says: ==================== 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. ==================== Signed-off-by: -

cap_max_headroom_size holds maximum headroom size supported. Overstepping that limit might under certain conditions lead to ASIC freeze. Query and store the value, and add mlxsw_sp_sb_max_headroom_cells() for obtaining the stored value. In __mlxsw_sp_port_headroom_set(), reject requests where the total port buffer is larger than the advertised maximum. Signed-off-by:

The recommendation for headroom size for 100Gbps port and 100m cable is 101.6KB, reduced accordingly for split ports. The closest higher number evenly divisible by cell size for both Spectrum-1 and Spectrum-2, and such that the number of cells can be further divided by maximum split factor of 4, is 102528 bytes, or 25632 bytes per lane. Update mlxsw_sp_port_pb_init() to compute the headroom taking into account this recommended per-lane value and number of lanes actually dedicated to a given port. Signed-off-by:

The SBPR register configures shared buffer pools. The default configuration depends on the chip type. Therefore keep it in struct mlxsw_sp_sb_vals. Redirect the one reference from the global array to the field. Because the pool descriptor ID is implicit in the ordering of array members, both this array and the pool descriptor array have the same length. Therefore reuse mlxsw_sp_sb.pool_dess_len for the purpose of determining the length of SBPR array. Drop the now useless MLXSW_SP_SB_PRS_LEN. Signed-off-by:

Commit 8fce3331 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. Changes from v2: - Only force restart transmission if there are pending packets Changes from v1: - Pass entire ring size to TX clean path (Florian) Signed-off-by:

Florian Fainelli says: ==================== 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 - tested bridge_vlan_aware.sh with veth/VRF ==================== Signed-off-by: -

With the bridge no longer calling switchdev_port_attr_get() to obtain the supported bridge port flags from a driver but instead trying to set the bridge port flags directly and relying on driver to reject unsupported configurations, we can effectively get rid of switchdev_port_attr_get() entirely since this was the only place where it was called.

Now that we have converted the bridge code and the drivers to check for bridge port(s) flags at the time we try to set them, there is no need for a get() -> set() sequence anymore and SWITCHDEV_ATTR_ID_PORT_BRIDGE_FLAGS_SUPPORT therefore becomes unused. Reviewed-by:
