2018-12-04octeontx2-af: Add LSO format configuration mailboxNithin Dabilpuram3-7/+91
NIX_AF_LSO_FORMAT(0..31)_FIELD(0..7) register enables an SW defined means to define LSO packet modification formats. 0..31 works as an index to choose the algorithm, On success, the mailbox returns the index to the client of chosen LSO algorithm selection. This index will be used in configuring the transmit descriptors. Add mailbox interface to dynamically reserve and configure LSO format. This commit also fixes 'sizem1' for NIX_LSOALG_TCP_FLAGS to '1' i.e 2 Bytes.

2018-12-04octeontx2-af: Add support for Tx packet markingKrzysztof Kanas3-0/+133
NIX_AF_MARK_FORMAT(0..127)_CTL register enables an SW defined means to mark/insert various data in the packet based on final packet color from traffic shaping HW. 0..127 works as an index to choose the algorithm. On success, the mailbox returns the index to the client. Add NIX_MARK_FORMAT_CFG mailbox which reserves mark format based on tuple (offset, y_mask, y_val, r_mask, r_val) If the tuple is requested again for mark format that was already reserved, then it will be reused. If not it will reserve a new entry if space is available. Also on AF init commonly used marker format such as VLAN DEI, IPv4 ECN, IPv4 DSCP are reserved for AF consumers.

2018-12-04octeontx2-af: Restrict TL1 allocation and configurationNithin Dabilpuram3-18/+218
TL1 is the root node in the scheduling hierarchy and it is a global resource with a limited number. This patch introduces restriction and validation on the allocation of the TL1 nodes for the effective resource sharing across the AF consumers. - Limit TL1 allocation to 2 per lmac. One could be for the normal link and one for IEEE802.3br express link (Express Send DMA). Effectively all the VF's of an RVU PF(lmac) share the two TL1 schqs. - TL1 cannot be freed once allocated. - Allow VF's to only apply default config to TL1 if not already applied. PF's can always overwrite the TL1 config. - Consider NIX_AQ_INSTOP_WRITE while validating txschq when sq.ena is set.

2018-12-04octeontx2-af: Add support for runtime RSS algo index reservationJerin Jacob4-94/+119
Introduced reserve_flowkey_alg_idx()to reserve RSS algorithm index, it would internally use set_flowkey_fields() to generate fields based on the flow key dynamically. On AF driver init, it would reserve a predefined set RSS algo indexes, which will be available all the time for all the AF driver consumers. The leftover algo indexes can be reserved at runtime through exiting nix_rss_flowkey_cfg mailbox message. The NIX_FLOW_KEY_TYPE_PORT is removed from predefined a set of RSS flow type as it is not used by any consumer. Signed-off-by: Jerin Jacob <jerinj@marvell.com> Signed-off-by: David S.

Introduce state-based algorithm to convert the flow_key value to RSS algo field used by NIX_AF_RX_FLOW_KEY_ALGX_FIELDX register. The outer `for loop` goes over _all_ protocol field and the following variables depict the state machine forward progress logic. a) keyoff_marker - Enabled when hash byte length needs to be accounted in field->key_offset update. b) field_marker - Enabled when a new field needs to be selected. c) group_member - Enabled when a protocol is part of a group.

2018-12-01mlxsw: spectrum: Enable VxLAN enslavement to VLAN-aware bridgesIdo Schimmel3-14/+404
Commit 1c30d1836aeb ("mlxsw: spectrum: Enable VxLAN enslavement to bridges") enabled the enslavement of VxLAN devices to bridges that have mlxsw ports (or their upper) as slaves. This patch extends mlxsw to also support VLAN-aware bridges. 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.

2018-12-01mlxsw: spectrum_switchdev: Prepare function for VLAN-aware bridgesIdo Schimmel3-9/+11
The vxlan_join() function resolves the FID on which the VNI should be set and then sets the VNI. Currently, the FID is simply resolved according to the ifindex of the bridge device to which the VxLAN device is enslaved. This works because only VLAN-unaware bridges are supported. With VLAN-aware bridges the FID would need to be resolved based on the VLAN to which the VNI is mapped to. Add the VLAN ID to the argument list of the function.

2018-12-01mlxsw: spectrum_switchdev: Unify VxLAN leave functionIdo Schimmel3-38/+9
The function mlxsw_sp_bridge_vxlan_leave() is currently split between VLAN-aware and VLAN-unaware bridges, but actually both types can use the same function. The function needs to resolve the FID that corresponds to the VxLAN device and disable NVE encapsulation on it. Instead of looking up the FID differently for VLAN-aware and VLAN-unaware bridges, we can always use the VxLAN's device VNI.

In a similar fashion to commit 564c6d727aca ("mlxsw: spectrum_fid: Add APIs to lookup FID without creating it"), add a corresponding API to lookup 802.1Q FIDs. This is a prerequisite to VxLAN support with VLAN-aware bridges and will allow us to resolve a 802.1Q FID by its VLAN when an FDB entry is added on the bridge port of the VxLAN device.
