…face counters (#6775) This PR is needed to fix the show interface counters output issue where the counters are not correct due to an issue introduced in BRCM SAI 4.3. - How to verify it Without the fix if one injects packets, the expected counters for the interfaces involved do not show correct count values. The RX count looks to be TX count while TX count looks to be RX count but even that the values could not be trusted. After the fix the counters started to look correct. Here is one sample output taken after the fix is applied where I manually injected 10,000 packets into Ethernet92 to be routed out of the port channel member port Ethernet40. Also injected 10,000 invalid packets into the same Ethernet92 and all 10,000 packets were shown RX_DRP correctly.

Why I did it
This PR is needed to fix the show interface counters output issue where the counters are not correct due to an issue introduced in BRCM SAI 4.3.
How to verify it
Without the fix if one injects packets, the expected counters for the interfaces involved do not show correct count values. The RX count looks to be TX count while TX count looks to be RX count but even that the values could not be trusted.
After the fix the counters started to look correct. Here is one sample output taken after the fix is applied where I manually injected 10,000 packets into Ethernet92 to be routed out of the port channel member port Ethernet40. Also injected 10,000 invalid packets into the same Ethernet92 and all 10,000 packets were shown RX_DRP correctly.
