Description

The issue is seen on 7800R3-48CQ2-LC,7800R3-48CQM2-LC, and 7800R3A-36DM2-LC. The command "sonic-clear queuecounters" doesn't clear up the VOQ counters which can be seen using the command "show queue counters --voq". However, the egress queue counters (show queue counters) still get cleared up.

Steps to reproduce the issue:

  1. Run traffic across the SONiC VOQ Chassis
  2. Verify the egress and voq counters using the commands "show queue counters ", "show queue counters --voq" respectively
  3. Clear the voq counters using the command "sonic-clear queuecounters"

[chassis][voq] clear: Fix clear queuecounters to also clear VOQ count…
5b492d5 
…ers (#2878)

Fix a bug where the CLI command sonic-clear queuecounters would not clear the VOQ counters.

fixes sonic-net/sonic-buildimage#15198

How I did it
Added the command to clear the VOQ counters.

How to verify it
Start traffic on an interface on a specific queue.
Use show queue counters and show queue counters --voq to verify that the counters are non-zero.
Stop traffic on the interface.
Run sonic-clear queuecounters.
Repeat the show commands and ensure that the counters have been reset.
