virtchnl: make proto and filter action count unsigned

2025-04-10T12:44:10Z

[ Upstream commit db5e8ea155fc1d89c87cb81f0e4a681a77b9b03f ] The count field in virtchnl_proto_hdrs and virtchnl_filter_action_set should never be negative while still being valid. Changing it from int to u32 ensures proper handling of values in virtchnl messages in driverrs and prevents unintended behavior. In its current signed form, a negative count does not trigger an error in ice driver but instead results in it being treated as 0. This can lead to unexpected outcomes when processing messages. By using u32, any invalid values will correctly trigger -EINVAL, making error detection more robust.

The kernel test robot reported a build failure on m68k in the intel driver due to the recent shapers-related changes.

virtchnl: support queue rate limit and quanta size configuration

2024-10-10T15:30:23Z

This patch adds new virtchnl opcodes and structures for rate limit and quanta size configuration, which include: 1. VIRTCHNL_OP_CONFIG_QUEUE_BW, to configure max bandwidth for each VF per queue. 2. VIRTCHNL_OP_CONFIG_QUANTA, to configure quanta size per queue. 3. VIRTCHNL_OP_GET_QOS_CAPS, VF queries current QoS configuration, such as enabled TCs, arbiter type, up2tc and bandwidth of VSI node. The configuration is previously set by DCB and PF, and now is the potential QoS capability of VF. VF can take it as reference to configure queue TC mapping.

iavf: add support for offloading tc U32 cls filters

2024-08-13T21:51:29Z

Add support for offloading cls U32 filters. Only "skbedit queue_mapping" and "drop" actions are supported. Also, only "ip" and "802_3" tc protocols are allowed. The PF must advertise the VIRTCHNL_VF_OFFLOAD_TC_U32 capability flag. Since the filters will be enabled via the FD stage at the PF, a new type of FDIR filters is added and the existing list and state machine are used. The new filters can be used to configure flow directors based on raw (binary) pattern in the rx packet. Examples: 0. # tc qdisc add dev enp175s0v0 ingress 1. Redirect UDP from src IP 192.168.2.1 to queue 12: # tc filter add dev protocol ip ingress u32 \ match u32 0x45000000 0xff000000 at 0 \ match u32 0x00110000 0x00ff0000 at 8 \ match u32 0xC0A80201 0xffffffff at 12 \ match u32 0x00000000 0x00000000 at 24 \ action skbedit queue_mapping 12 skip_sw 2. Drop all ICMP: # tc filter add dev protocol ip ingress u32 \ match u32 0x45000000 0xff000000 at 0 \ match u32 0x00010000 0x00ff0000 at 8 \ match u32 0x00000000 0x00000000 at 24 \ action drop skip_sw 3. Redirect ICMP traffic from MAC 3c:fd:fe:a5:47:e0 to queue 7 (note proto: 802_3): # tc filter add dev protocol 802_3 ingress u32 \ match u32 0x00003CFD 0x0000ffff at 4 \ match u32 0xFEA547E0 0xffffffff at 8 \ match u32 0x08004500 0xffffff00 at 12 \ match u32 0x00000001 0x000000ff at 20 \ match u32 0x0000 0x0000 at 40 \ action skbedit queue_mapping 7 skip_sw Notes on matches: 1 - All intermediate fields that are needed to parse the correct PTYPE must be provided (in e.g. 3: Ethernet Type 0x0800 in MAC, IP version and IP length: 0x45 and protocol: 0x01 (ICMP)). 2 - The last match must provide an offset that guarantees all required headers are accounted for, even if the last header is not matched. For example, in #2, the last match is 4 bytes at offset 24 starting from IP header, so the total is 14 (MAC) + 24 + 4 = 42, which is the sum of MAC+IP+ICMP headers.

virtchnl: support raw packet in protocol header

2024-08-13T21:51:28Z

The patch extends existing virtchnl_proto_hdrs structure to allow VF to pass a pair of buffers as packet data and mask that describe a match pattern of a filter rule. Then the kernel PF driver is requested to parse the pair of buffer and figure out low level hardware metadata (ptype, profile, field vector.. ) to program the expected FDIR or RSS rules.

iavf: enable symmetric-xor RSS for Toeplitz hash function

2023-12-14T06:07:17Z

Allow the user to set the symmetric Toeplitz hash function via: # ethtool -X eth0 hfunc toeplitz symmetric-xor The driver will reject any new RSS configuration if a field other than (IP src/dst and L4 src/dst ports) is requested for hashing. The symmetric RSS will not be supported on PFs not advertising the ADV RSS Offload flag (ADV_RSS_SUPPORT()), for example the E700 series (i40e).

ice: refactor RSS configuration

2023-12-14T06:07:17Z

Refactor the driver to use a communication data structure for RSS config. To do so we introduce the new ice_rss_hash_cfg struct, and then pass it as an argument to several functions. Also introduce enum ice_rss_cfg_hdr_type to specify a more granular and flexible RSS configuration: ICE_RSS_OUTER_HEADERS - take outer layer as RSS input set ICE_RSS_INNER_HEADERS - take inner layer as RSS input set ICE_RSS_INNER_HEADERS_W_OUTER_IPV4 - take inner layer as RSS input set for packet with outer IPV4 ICE_RSS_INNER_HEADERS_W_OUTER_IPV6 - take inner layer as RSS input set for packet with outer IPV6 ICE_RSS_ANY_HEADERS - try with outer first then inner (same as the behaviour without this change) Finally, move the virtchnl_rss_algorithm enum to be with the other RSS related structures in the virtchnl.h file. There should be no functional change due to this patch.

The VF already sends information about configuring its RX queues so use that structure to indicate that the CRC stripping should be enabled or not.
