This patch supports telemetry querying flow control info.
The command is like:
--> /ethdev/flow_ctrl,0
{
"/ethdev/flow_ctrl": {
"high_waterline": "0x0",
"low_waterline": "0x0",
"pause_time": "0xffff",
"send_xon": "off",
"mac_ctrl_frame_fwd": "off",
"rx_pause": "off",
"tx_pause": "off",
"autoneg": "off"
}
}
