Hi All,
Below are the configuration and patch details which provides the support
for clearing statistics at Interface level.
Description & Configuration:
OVS by default has the support for the command ovs-vsctl clear interface <name>
statistics
But in OVS the command functionality is implemented in such a way that we are
just
clearing the key and values and Number of statistics fields respective to the
statistics
column of Interface table at the db level, which was not clearing the
statistics at
Hardware level so we have extended the support to clear the statistics at
Hardware level.
Please find the below patch for implementation of clear statistics at Interface
level.
