[PATCH net-next 0/2] net: stmmac: add EthType Rx Frame steering

[Ong Boon Leong]

Hi,

Patch 1/2: Fixes issue in tc filter delete flower for VLAN priority
           steering. Patch has been sent to 'net' ML. Link as follow:

https://patchwork.kernel.org/project/netdevbpf/patch/20211209130335.81114-1-boon.leong.ong@intel.com/

Patch 2/2: Patch to add LLDP and IEEE1588 EtherType RX frame steering
           in tc flower that is implemented on-top of patch 1/2.

Below are the test steps for checking out the newly added feature:-

# Setup traffic class and ingress filter
$ IFDEVNAME=eth0
$ tc qdisc add dev $IFDEVNAME ingress
$ tc qdisc add dev $IFDEVNAME root mqprio num_tc 8 \
     map 0 1 2 3 4 5 6 7 0 0 0 0 0 0 0 0 \
     queues 1 at 0 1 at 1 1 at 2 1 at 3 1 at 4 1 at 5 1 at 6 1 at 7 hw 0

# Add two VLAN priority based RX Frame Steering
$ tc filter add dev $IFDEVNAME parent ffff: protocol 802.1Q \
     flower vlan_prio 1 hw_tc 1
$ tc filter add dev $IFDEVNAME parent ffff: protocol 802.1Q \
     flower vlan_prio 2 hw_tc 2

# For LLDP
$ tc filter add dev $IFDEVNAME parent ffff: protocol 0x88cc \
     flower hw_tc 5

# For PTP
$ tc filter add dev $IFDEVNAME parent ffff: protocol 0x88f7 \
     flower hw_tc 6

# Show the ingress tc filters
$ tc filter show dev $IFDEVNAME ingress

filter parent ffff: protocol ptp pref 49149 flower chain 0
filter parent ffff: protocol ptp pref 49149 flower chain 0 handle 0x1 hw_tc 6
  eth_type 88f7
  in_hw in_hw_count 1
filter parent ffff: protocol LLDP pref 49150 flower chain 0
filter parent ffff: protocol LLDP pref 49150 flower chain 0 handle 0x1 hw_tc 5
  eth_type 88cc
  in_hw in_hw_count 1
filter parent ffff: protocol 802.1Q pref 49151 flower chain 0
filter parent ffff: protocol 802.1Q pref 49151 flower chain 0 handle 0x1 hw_tc 2
  vlan_prio 2
  in_hw in_hw_count 1
filter parent ffff: protocol 802.1Q pref 49152 flower chain 0
filter parent ffff: protocol 802.1Q pref 49152 flower chain 0 handle 0x1 hw_tc 1
  vlan_prio 1
  in_hw in_hw_count 1

# Delete tc filters
$ tc filter del dev $IFDEVNAME parent ffff: pref 49149
$ tc filter del dev $IFDEVNAME parent ffff: pref 49150
$ tc filter del dev $IFDEVNAME parent ffff: pref 49151
$ tc filter del dev $IFDEVNAME parent ffff: pref 49152

Thanks,
