[2405][BRCM-DNX]: 'sonic-clear queuecounter' CLI does not clear the queue counters.

[amitpawar12]

Description

This is regression in 2405 as compared to release 2205.

We are using CLI - 'sudo ip netns exec asic<0/1> sonic-clear queuecounter' to clear the queue counter. The same CLI was used in 2205 to clear the counters.

However, in 2405, this CLI does not clear the counter.

Note - there is an on-going discussion about 'show ...' CLIs involved in multi-asic environment. However, the clear commands should also be addressed. This issue is a placeholder to ensure that we address this issue.

Steps to reproduce the issue:

1. Send traffic to one of the ports.
2. Check the queue counters on the egress ASIC.
3. Ensure that counters are non-zero.

admin@ixre-egl-board72:~$ sudo ip netns exec asic0 show queue counter --nonzero

4. Clear the counters and check the counters.

admin@ixre-egl-board72:~$ sudo ip netns exec asic0 sonic-clear queuecounter
Clear and update saved counters for Ethernet0
Clear and update saved counters for Ethernet8
Clear and update saved counters for Ethernet16
Clear and update saved counters for Ethernet24
Clear and update saved counters for Ethernet32
Clear and update saved counters for Ethernet40
------------- curtailed output ------------

5. In 2205, the counters will be reset to zero. However, in 2405, this does not happen.

admin@ixre-egl-board72:~$ sudo ip netns exec asic0 show queue counter --nonzero
