      net: stmmac: Add EST errors into ethtool statistic · 9f298959
      Ong Boon Leong authored
      Below EST errors are added into ethtool statistic:
      1) Constant Gate Control Error (CGCE):
         The counter "mtl_est_cgce" increases everytime CGCE interrupt is
         triggered.
      
      2) Head-of-Line Blocking due to Scheduling (HLBS):
         The counter "mtl_est_hlbs" increases everytime HLBS interrupt is
         triggered.
      
      3) Head-of-Line Blocking due to Frame Size (HLBF):
         The counter "mtl_est_hlbf" increases everytime HLBF interrupt is
         triggered.
      
      4) Base Time Register error (BTRE):
         The counter "mtl_est_btre" increases everytime BTRE interrupt is
         triggered but BTRL not reaches maximum value of 15.
      
      5) Base Time Register Error Loop Count (BTRL) reaches maximum value:
         The counter "mtl_est_btrlm" increases everytime BTRE interrupt is
         triggered and BTRL value reaches maximum value of 15.
      
      Please refer to MTL_EST_STATUS register in DesignWare Cores Ethernet
      Quality-of-Service Databook for more detail explanation.

      Voon Weifeng authored
      Enabled EST related interrupts as below:
      1) Constant Gate Control Error (CGCE)
      2) Head-of-Line Blocking due to Scheduling (HLBS)
      3) Head-of-Line Blocking due to Frame Size (HLBF).
      4) Base Time Register error (BTRE)
      5) Switch to S/W owned list Complete (SWLC)
      
      For HLBS, the user will get the info of all the queues that shows this
      error. For HLBF, the user will get the info of all the queue with the
      latest frame size which causes the error. Frame size 0 indicates no
      error.
      
      The ISR handling takes place when EST feature is enabled by user.

      stmmac: add VLAN priority based RX steering
      
      The current tc flower implementation in stmmac supports both L3 and L4
      filter offloading. This patch adds the support of VLAN priority based
      RX frame steering into different Rx Queues.
      
      The patches have been tested on both configuration test (include L3/L4)
      and traffic test (multi VLAN ping streams with RX Frame Steering) below:-

      net: stmmac: add RX frame steering based on VLAN priority in tc flower · 0e039f5c
      Ong Boon Leong authored
      We extend tc flower to support configuration of VLAN priority-based RX
      frame steering hardware offloading.
      
      To map VLAN <PCP> to Traffic Class <TC>:
        $ tc filter add dev <IFNAME> parent ffff: protocol 802.1Q flower \
             vlan_prio <PCP> hw_tc <TC>
      
        Note: <TC> < N whereby "tc qdisc ... num_tc N ..."
      
      To delete all tc flower configurations:
        $ tc qdisc delete dev <IFNAME> ingress

      net: stmmac: restructure tc implementation for RX VLAN Priority steering · bd0f670e
      Ong Boon Leong authored
      The current tc_add_flow() and tc_del_flow() use hardware L3 & L4 filters
      as offloading. The number of L3/L4 filters is read from L3L4FNUM field
      from MAC_HW_Feature1 register and is used to alloc priv->tc_entries[].
      
      For RX frame steering based on VLAN priority offloading, we use
      MAC_RXQ_CTRL2 & MAC_RXQ_CTRL3 registers and all VLAN priority level
      can be configured independent from L3 & L4 filters.

      ====================
      Add tc hardware offloads
      
      This patch series adds support for tc hardware offloads.
      
      Patch #1 adds support for offloading flows that matches IP tos and IP
               protocol which will be used by tc hw offload support. Also
               added ethtool n-tuple filter to code to offload the flows
               matching the above fields.
      Patch #2 adds tc flower hardware offload support on ingress traffic.
      Patch #3 adds TC flower offload stats.
      Patch #4 adds tc TC_MATCHALL egress ratelimiting offload.
      
      * tc flower hardware offload in PF driver
      
      The driver parses the flow match fields and actions received from the tc
      subsystem and adds/delete MCAM rules for the same. Each flow contains set
      of match and action fields. If the action or fields are not supported,
      the rule cannot be offloaded to hardware. The tc uses same set of MCAM
      rules allocated for ethtool n-tuple filters. So, at a time only one entity
      can offload the flows to hardware, they're made mutually exclusive in the
      driver.
      
      Following match and actions are supported.
      
      Match: Eth dst_mac, EtherType, 802.1Q {vlan_id,vlan_prio}, vlan EtherType,
             IP proto {tcp,udp,sctp,icmp,icmp6}, IPv4 tos, IPv4{dst_ip,src_ip},
             L4 proto {dst_port|src_port number}.
      Actions: drop, accept, vlan pop, redirect to another port on the device.
      
      The Hardware stats are also supported. Currently only packet counter stats
      are updated.
      
      * tc egress rate limiting support
      Added TC-MATCHALL classifier offload with police action applied for all
      egress traffic on the specified interface.

      octeontx2-pf: TC_MATCHALL egress ratelimiting offload · e638a83f
      Sunil Goutham authored
      Add TC_MATCHALL egress ratelimiting offload support with POLICE
      action for entire traffic going out of the interface.
      
      Eg: To ratelimit egress traffic to 100Mbps
      
      $ ethtool -K eth0 hw-tc-offload on
      $ tc qdisc add dev eth0 clsact
      $ tc filter add dev eth0 egress matchall skip_sw \
                      action police rate 100Mbit burst 16Kbit
      
      HW supports a max burst size of ~128KB.
      Only one ratelimiting filter can be installed at a time.

      octeontx2-pf: add tc flower stats handler for hw offloads · d8ce30e0
      Naveen Mamindlapalli authored
      Add support to get the stats for tc flower flows that are
      offloaded to hardware. To support this feature, added a
      new AF mbox handler which returns the MCAM entry stats
      for a flow that has hardware stat counter enabled.

      octeontx2-pf: Add tc flower hardware offload on ingress traffic · 1d4d9e42
      Naveen Mamindlapalli authored
      This patch adds support for tc flower hardware offload on ingress
      traffic. Since the tc-flower filter rules use the same set of MCAM
      rules as the n-tuple filters, the n-tuple filters and tc flower
      rules are mutually exclusive. When one of the feature is enabled
      using ethtool, the other feature is disabled in the driver. By default
      the driver enables n-tuple filters during initialization.
      
      The following flow keys are supported.
          -> Ethernet: dst_mac
          -> L2 proto: all protocols
          -> VLAN (802.1q): vlan_id/vlan_prio
          -> IPv4: dst_ip/src_ip/ip_proto{tcp|udp|sctp|icmp}/ip_tos
          -> IPv6: ip_proto{icmpv6}
          -> L4(tcp/udp/sctp): dst_port/src_port
      
      The following flow actions are supported.
          -> drop
          -> accept
          -> redirect
          -> vlan pop
      
      The flow action supports multiple actions when vlan pop is specified
      as the first action. The redirect action supports redirecting to the
      PF/VF of same PCI device. Redirecting to other PCI NIX devices is not
      supported.
      
      Example #1: Add a tc filter rule to drop UDP traffic with dest port 80
          # ethtool -K eth0 hw-tc-offload on
          # tc qdisc add dev eth0 ingress
          # tc filter add dev eth0 protocol ip parent ffff: flower ip_proto \
                udp dst_port 80 action drop
      
      Example #2: Add a tc filter rule to redirect ingress traffic on eth0
      with vlan id 3 to eth6 (ex: eth0 vf0) after stripping the vlan hdr.
          # ethtool -K eth0 hw-tc-offload on
          # tc qdisc add dev eth0 ingress
          # tc filter add dev eth0 parent ffff: protocol 802.1Q flower \
                vlan_id 3 vlan_ethtype ipv4 action vlan pop action mirred \
                ingress redirect dev eth6
      
      Example #3: List the ingress filter rules
          # tc -s filter show dev eth4 ingress
      
      Example #4: Delete tc flower filter rule with handle 0x1
          # tc filter del dev eth0 ingress protocol ip pref 49152 \
            handle 1 flower

      octeontx2-pf: Add ip tos and ip proto icmp/icmpv6 flow offload support · 2b9cef66
      Naveen Mamindlapalli authored
      Add support for programming the HW MCAM match key with IP tos, IP(v6)
      proto icmp/icmpv6, allowing flow offload rules to be installed using
      those fields. The NPC HW extracts layer type, which will be used as a
      matching criteria for different IP protocols.
      
      The ethtool n-tuple filter logic has been updated to parse the IP tos
      and l4proto for HW offloading. l4proto tcp/udp/sctp/ah/esp/icmp are
      supported. See example usage below.
      
      Ex: Redirect l4proto icmp to vf 0 queue 0
      ethtool -U eth0 flow-type ip4 l4proto 1 action vf 0 queue 0
      
      Ex: Redirect flow with ip tos 8 to vf 0 queue 0
      ethtool -U eth0 flow-type ip4 tos 8 vf 0 queue 0
