Add support for the BRIDGE_XSTATS_STP xstats, as follow:
# ip link xstats type bridge_slave dev lan4 stp
lan4
STP BPDU: RX: 0 TX: 61
STP TCN: RX: 0 TX: 0
STP Transitions: Blocked: 2 Forwarding: 1
Or below as JSON:
# ip -j -p link xstats type bridge_slave dev lan0 stp
[ {
"ifname": "lan0",
"stp": {
"rx_bpdu": 0,
"tx_bpdu": 500,
"rx_tcn": 0,
"tx_tcn": 0,
"transition_blk": 0,
"transition_fwd": 0
}
} ]
