Implement and export UDP segmentation offload (USO) support for both NIC and MQPRIO QoS offload Tx path.

2019-11-22cxgb4/chcr: update SGL DMA unmap for USORahul Lakkireddy3-101/+39
The FW_ETH_TX_EO_WR used for sending UDP Segmentation Offload (USO) requests expects the headers to be part of the descriptor and the payload to be part of the SGL containing the DMA mapped addresses. Hence, the DMA address in the first entry of the SGL can start after the packet headers. Currently, unmap_sgl() tries to unmap from this wrong offset, instead of the originally mapped DMA address. So, use existing unmap_skb() instead, which takes originally saved DMA addresses as input. Update all necessary Tx paths to save the original DMA addresses, so that unmap_skb() can unmap them properly. v2: - No change.

2019-11-20cxgb4: add TC-MATCHALL classifier ingress offloadRahul Lakkireddy6-19/+192
Add TC-MATCHALL classifier ingress offload support. The same actions supported by existing TC-FLOWER offload can be applied to all incoming traffic on the underlying interface. Ensure the rule priority doesn't conflict with existing rules in the TCAM. Only 1 ingress matchall rule can be active at a time on the underlying interface. v5: - No change. v4: - Added check to ensure the matchall rule's prio doesn't conflict with other rules in TCAM. - Added logic to fill default mask for VIID, if none has been provided, to prevent conflict with duplicate VIID rules. - Used existing variables in private structure to fill VIID info, instead of extracting the info manually. v3: - No change. v2: - Removed logic to fetch free index from end of TCAM. Must maintain same ordering as in kernel. Signed-off-by: Rahul Lakkireddy <rahul.lakkireddy@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-11-20cxgb4: check rule prio conflicts before offloadRahul Lakkireddy5-44/+143
Only offload rule if it satisfies both of the following conditions: 1. The immediate previous rule has priority <= current rule's priority. 2. The immediate next rule has priority >= current rule's priority. Also rework free entry fetch logic to search from end of TCAM, instead of beginning, because higher indices have lower priority than lower indices. This is similar to how TC auto generates priority values. v5: - Fixed commit message and comment to include comparison for equal priority. v4: - Patch added in this version.

2019-11-20cxgb4: add TC-MATCHALL classifier egress offloadRahul Lakkireddy9-33/+381
Add TC-MATCHALL classifier offload with TC-POLICE action applied for all outgoing traffic on the underlying interface. Split flow block offload to support both egress and ingress classification. For example, to rate limit all outgoing traffic to 1 Gbps: $ tc qdisc add dev enp2s0f4 clsact $ tc filter add dev enp2s0f4 egress matchall skip_sw \ action police rate 1Gbit burst 8Kbit Note that skip_sw is important. Otherwise, both stack and hardware will end up doing policing. Policing can't be shared across flow blocks. Only 1 egress matchall rule can be active at a time on the underlying interface. v5: - No change. v4: - Removed check to reject police offload if prio is not 1. - Moved TC_SETUP_BLOCK code to separate function. v3: - Added check to reject police offload if prio is not 1. - Assign block_shared variable only for TC_SETUP_BLOCK. v2: - Added check to reject flow block sharing for policers.

2019-11-07cxgb4: add FLOWC based QoS offloadRahul Lakkireddy7-53/+495
Rework SCHED API to allow offloading TC-MQPRIO QoS configuration. The existing QUEUE based rate limiting throttles all queues sharing a traffic class, to the specified max rate limit value. So, if multiple queues share a traffic class, then all the queues get the aggregate specified max rate limit. So, introduce the new FLOWC based rate limiting, where multiple queues can share a traffic class with each queue getting its own individual specified max rate limit. For example, if 2 queues are bound to class 0, which is rate limited to 1 Gbps, then 2 queues using QUEUE based rate limiting, get the aggregate output of 1 Gbps only. In FLOWC based rate limiting, each queue gets its own output of max 1 Gbps each; i.e. 2 queues * 1 Gbps rate limit = 2 Gbps.

2019-10-25cxgb4: request the TX CIDX updates to status pageRaju Rangoju1-6/+2
For adapters which support the SGE Doorbell Queue Timer facility, we configured the Ethernet TX Queues to send CIDX Updates to the Associated Ethernet RX Response Queue with CPL_SGE_EGR_UPDATE messages to allow us to respond more quickly to the CIDX Updates. But, this was adding load to PCIe Link RX bandwidth and, potentially, resulting in higher CPU Interrupt load. This patch requests the HW to deliver the CIDX updates to the TX queue status page rather than generating an ingress queue message (as an interrupt). With this patch, the load on RX bandwidth is reduced and a substantial improvement in BW is noticed at lower IO sizes.

When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this. If a debugfs call fails, it will properly warn in the syslog, there's no need for all individual drivers to also print a message, so that is one more reason to not care about checking the return values.
