* bnxt_en: Add DCBNL DSCP application protocol support.Michael Chan2018-08-051-0/+1
| | | | | | | | | | | Expand the .ieee_setapp() and ieee_delapp() DCBNL methods to support DSCP. This allows DSCP values to user priority mappings instead of using VLAN priorities. Each DSCP mapping is added or deleted one entry at a time using the firmware API. The firmware call can only be made from a PF.

* bnxt_en: Update RSS setup and GRO-HW logic according to the latest spec.Michael Chan2018-08-051-0/+4
| | | | | | | | | | | | | Set the default hash mode flag in HWRM_VNIC_RSS_CFG to signal to the firmware that the driver is compliant with the latest spec. With that, the firmware can return expanded RSS profile IDs that the driver checks to setup the proper gso_type for GRO-HW packets. But instead of checking for the new profile IDs, we check the IP_TYPE flag in TPA_START which is more straight forward than checking a list of profile IDs.

| * bnxt_en: Do not modify max IRQ count after RDMA driver requests/frees IRQs.Michael Chan2018-07-091-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Calling bnxt_set_max_func_irqs() to modify the max IRQ count requested or freed by the RDMA driver is flawed. The max IRQ count is checked when re-initializing the IRQ vectors and this can happen multiple times during ifup or ethtool -L. If the max IRQ is reduced and the RDMA driver is operational, we may not initailize IRQs correctly. This problem shows up on VFs with very small number of MSIX. There is no other logic that relies on the IRQ count excluding the ones used by RDMA. So we fix it by just removing the call to subtract or add the IRQs used by RDMA.

| | | | | | | | | | | | | | | | | | For SFP+ modules, 0xA2 page is available only when Diagnostic Monitoring Type [Address A0h, Byte 92] is implemented. Extend bnxt_get_module_info(), to read optical diagnostics support at offset 92(0x5c) and set eeprom_len length to ETH_MODULE_SFF_8436_LEN (to exclude A2 page), if dianostics is not supported. Also in bnxt_get_module_info(), module id is read from offset 0x5e which is not correct. It was working by accident, as offset was not effective without setting enables flag in the firmware request.

* bnxt_en: Fix firmware message delay loop regression.Michael Chan2018-05-081-0/+7
| | | | | | | | | | | | | | | | | | A recent change to reduce delay granularity waiting for firmware reponse has caused a regression. With a tighter delay loop, the driver may see the beginning part of the response faster. The original 5 usec delay to wait for the rest of the message is not long enough and some messages are detected as invalid. Increase the maximum wait time from 5 usec to 20 usec. Also, fix the debug message that shows the total delay time for the response when the message times out. With the new logic, the delay time is not fixed per iteration of the loop, so we define a macro to show the total delay time.

* bnxt_en: Add TC to hardware QoS queue mapping logic.Michael Chan2018-04-271-0/+1
| | | | | | | | | | | | | | | | | | | | The current driver maps MQPRIO traffic classes directly 1:1 to the internal hardware queues (TC0 maps to hardware queue 0, etc). This direct mapping requires the internal hardware queues to be reconfigured from lossless to lossy and vice versa when necessary. This involves reconfiguring internal buffer thresholds which is disruptive and not always reliable. Implement a new scheme to map TCs to internal hardware queues by matching up their PFC requirements. This will eliminate the need to reconfigure a hardware queue internal buffers at run time. After remapping, the NIC is closed and opened for the new TC to hardware queues to take effect. This patch only adds the basic mapping logic.

* bnxt_en: Improve ring allocation logic.Michael Chan2018-03-311-0/+4
| | | | | | | | | | | | | | | | | | Currently, the driver code makes some assumptions about the group index and the map index of rings. This makes the code more difficult to understand and less flexible. Improve it by adding the grp_idx and map_idx fields explicitly to the bnxt_ring_struct as a union. The grp_idx is initialized for each tx ring and rx agg ring during init. time. We do the same for the map_idx for each cmpl ring. The grp_idx ties the tx ring to the ring group. The map_idx is the doorbell index of the ring. With this new infrastructure, we can change the ring index mapping scheme easily in the future.

| | | | | | | | | | | | When checking for the maximum pre-set TX channels for ethtool -l, we need to check the current max_tx_scheduler_inputs parameter from firmware. This parameter specifies the max input for the internal QoS nodes currently available to this function. The function's TX rings will be capped by this parameter. By adding this logic, we provide a more accurate pre-set max TX channels to the user. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

This way, there is more flexibility for each VF to allocate more or less resources. The min is the absolute minimum for each VF to function. The max is the global resources minus the resources used by the PF. Each VF is guaranteed the min. Up to max resources may be available for some VFs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds IPv4 vxlan encap/decap action support to TC-flower offload. For vxlan encap, the driver maintains a tunnel encap hash-table. When a new flow with a tunnel encap action arrives, this table is looked up; if an encap entry exists, it uses the already programmed encap_record_handle as the tunnel_handle in the hwrm_cfa_flow_alloc cmd. Else, a new encap node is added and the L2 header fields are queried via a route lookup. hwrm_cfa_encap_record_alloc cmd is used to create a new encap record and the encap_record_handle is used as the tunnel_handle while adding the flow. For vxlan decap, the driver maintains a tunnel decap hash-table. When a new flow with a tunnel decap action arrives, this table is looked up; if a decap entry exists, it uses the already programmed decap_filter_handle as the tunnel_handle in the hwrm_cfa_flow_alloc cmd. Else, a new decap node is added and a decap_filter_handle is alloc'd via the hwrm_cfa_decap_filter_alloc cmd. This handle is used as the tunnel_handle while adding the flow.

* bnxt_en: assign CPU affinity hints to bnxt_en IRQsVasundhara Volam2017-08-281-1/+3
| | | | | | | | | | | This patch provides hints to irqbalance to map bnxt_en device IRQs to specific CPU cores. cpumask_local_spread() is used, which first maps IRQs to near NUMA cores; when those cores are exhausted, IRQs are mapped to far NUMA cores.

* bnxt_en: Improve tx ring reservation logic.Michael Chan2017-08-281-2/+3
| | | | | | | | | | | | | | | | | | | | | | | When the number of TX rings is changed (e.g. ethtool -L, enabling XDP TX rings, etc), the current code tries to reserve the new number of TX rings before closing and re-opening the NIC. If we are unable to reserve the new TX rings, we abort the operation and keep the current TX rings. The problem is that the firmware will disable the current TX rings even when it cannot reserve the new set of TX rings. We fix it as follows: 1. Instead of reserving the new set of TX rings, just ask the firmware to check if the new set of TX rings is available. There is a flag in the firmware message to do that. If not available, abort and the current TX rings will not be disabled. 2. Do the actual TX ring reservation in the path that opens the NIC. We keep the number of TX rings currently successfully reserved. If the number of TX rings is different than the reserved TX rings, we call firmware and reserve again.

* bnxt_en: add support for port_attr_get and and get_phys_port_nameSathya Perla2017-07-241-0/+2
| | | | | | | | | | | This patch adds support for the switchdev_port_attr_get() and ndo_get_phys_port_name() methods for the PF and the VF-reps. Using this support a user application can deduce that the PF (when in the ESWITCH_SWDEV mode) and it's VF-reps form a switch.
