[PATCH for 7.0 V10 1/6] qapi/net: Add IPFlowSpec and QMP command for filter passthrough |
Date: |
Fri, 12 Nov 2021 11:11:07 +0800 |
Since the real user scenario does not need to monitor all traffic.
Add passthrough-filter-add and passthrough-filter-del to maintain
a network passthrough list in object with network packet processing
function. Add IPFlowSpec struct for all QMP commands.
Most the fields of IPFlowSpec are optional,except object-name.
