Hi Mathieu
This already works with DSA. I have a WRT1900AC which has a 7 port
switch. With DSA i have:
# ip link show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 532
link/ether 94:10:3e:80:bc:f3 brd ff:ff:ff:ff:ff:ff
3: eth1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 532
link/ether 52:33:3a:a7:c1:8a brd ff:ff:ff:ff:ff:ff
4: lan4@eth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default
link/ether 94:10:3e:80:bc:f3 brd ff:ff:ff:ff:ff:ff
5: lan3@eth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default
link/ether 94:10:3e:80:bc:f3 brd ff:ff:ff:ff:ff:ff
6: lan2@eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT group default
link/ether 94:10:3e:80:bc:f3 brd ff:ff:ff:ff:ff:ff
7: lan1@eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT group default
link/ether 94:10:3e:80:bc:f3 brd ff:ff:ff:ff:ff:ff
8: internet@eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT group default
link/ether 94:10:3e:80:bc:f3 brd ff:ff:ff:ff:ff:ff
internet would be your WAN port in your diagram. I just named it the
same as the label on the case.
I can get MIB statistics in the normal way for the DSA ports, e.g:
root@wrt1900ac:~# ethtool -S lan1
NIC statistics:
tx_packets: 153009
tx_bytes: 13307317
rx_packets: 161136
rx_bytes: 21840683
...
