* qed/qede: Multi CoS support.Manish Chopra2018-08-091-0/+6
| | | | | | | | | | | | | | | | | This patch adds support for tc mqprio offload, using this different traffic classes on the adapter can be utilized based on configured priority to tc map. For example - tc qdisc add dev eth0 root mqprio num_tc 4 map 0 1 2 3 This will cause SKBs with priority 0,1,2,3 to transmit over tc 0,1,2,3 hardware queues respectively.

* qed*: Support other classification modes.Manish Chopra2018-05-251-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | Currently, driver supports flow classification to PF receive queues based on TCP/UDP 4 tuples [src_ip, dst_ip, src_port, dst_port] only. This patch enables to configure different flow profiles [For example - only UDP dest port or src_ip based] on the adapter so that classification can be done according to just those fields as well. Although, at a time just one type of flow configuration is supported due to limited number of flow profiles available on the device. For example - ethtool -N enp7s0f0 flow-type udp4 dst-port 45762 action 2 ethtool -N enp7s0f0 flow-type tcp4 src-ip 192.16.4.10 action 1 ethtool -N enp7s0f0 flow-type udp6 dst-port 45762 action 3 Signed-off-by: Manish Chopra <manish.chopra@cavium.com> Signed-off-by: Shahed Shaikh <shahed.shaikh@cavium.com> Signed-off-by: Ariel Elior <ariel.elior@cavium.com> Signed-off-by: David S.

* qed* : Add new TLV to request PF to update MAC in bulletin boardShahed Shaikh2018-04-201-0/+1
| | | | | | | | | | | | | | | | | There may be a need for VF driver to request PF to explicitly update its bulletin with a MAC address. e.g. When user assigns a MAC address to VF while VF is still down, and PF's bulletin board contains different MAC address, in this case, when VF's interface is brought up, it gets loaded with MAC address from bulletin board which is not desirable. To handle this corner case, we need a new TLV to request PF to update its bulletin board with suggested MAC. This request will be honored only for trusted VFs.

* qed*: Fix issues in the ptp filter config implementation.sudarsana.kalluru@cavium.com2017-05-021-6/+17
| | | | | | | | | | | | | | | | | | | | | PTP hardware filter configuration performed by the driver for a given user requested config is not correct for some of the PTP modes. Following changes are needed for PTP config-filter implementation. 1. NIG_REG_TX_PTP_EN register - Bits 0/1/2 respectively enables TimeSync/"V1 frame format support"/"V2 frame format support" on the TX side. Set the associated bits based on the user request. 2. ptp4l application fails to operate in Peer Delay mode. Following changes are needed to fix this, a. Driver should enable (set to 0) DA #1-related bits for IPv4, IPv6 and MAC destination addresses in these registers: NIG_REG_TX_LLH_PTP_RULE_MASK NIG_REG_LLH_PTP_RULE_MASK b. NIG_REG_LLH_PTP_PARAM_MASK/NIG_REG_TX_LLH_PTP_PARAM_MASK should be set to 0x0 in all modes.

* qed*: Handle-based L2-queues.Mintz, Yuval2016-11-301-27/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver needs to maintain several FW/HW-indices for each one of its queues. Currently, that mapping is done by the QED where it uses an rx/tx array of so-called hw-cids, populating them whenever a new queue is opened and clearing them upon destruction of said queues. This maintenance is far from ideal - there's no real reason why QED needs to maintain such a data-structure. It becomes even worse when considering the fact that the PF's queues and its child VFs' queues are all mapped into the same data-structure. As a by-product, the set of parameters an interface needs to supply for queue APIs is non-trivial, and some of the variables in the API structures have different meaning depending on their exact place in the configuration flow. This patch re-organizes the way L2 queues are configured and maintained. In short: - Required parameters for queue init are now well-defined. - Qed would allocate a queue-cid based on parameters. Upon initialization success, it would return a handle to caller. - Queue-handle would be maintained by entity requesting queue-init, not necessarily qed. - All further queue-APIs [update, destroy] would use the opaque handle as reference for the queue instead of various indices. The possible owners of such handles: - PF queues [qede] - complete handles based on provided configuration. - VF queues [qede] - fw-context-less handles, containing only relative information; Only the PF-side would need the absolute indices for configuration, so they're omitted here. - VF queues [qed, PF-side] - complete handles based on VF initialization.

* qed: Learn resources from management firmwareTomer Tayar2016-10-311-1/+1
| | | | | | | | | | | | | | | Currently, each interfaces assumes it receives an equal portion of HW/FW resources, but this is wasteful - different partitions [and specifically, parititions exposing different protocol support] might require different resources.

* qed*: Allow unicast filteringYuval Mintz2016-10-141-0/+1
| | | | | | | | | | | Apparently qede fails to set IFF_UNICAST_FLT, and as a result is not actually performing unicast MAC filtering.

The major differences would be in: - Recognizing that VF is running on top of a legacy PF. - Returning some slowpath configurations that are no longer needed on top of modern PFs, but would be required when working over the legacy ones.
