Sample Rate on mirror		Innovium	BRCM/ LinkedIn		Ability to sample on a mirror. i.e, instead of mirroring all the packets, just send 1 out of n packets. This involves adding SONiC support  for Mirror session attribute SAI_MIRROR_SESSION_ATTR_SAMPLE_RATE.	No	Low

V4/V6 L3 ACL optimization	March	Innovium	BRCM/ LinkedIn		Currently SONiC uses separate ACL tables for L3 and L3v6 RACLs. In some ASICs, if a user wants both v4 and v6 rules, they would end up using two hardware ACL tables instead of one. The proposal is to give the platform the ability to mention if they want to support L3 and L3V6 ACLs in the same hardware ACL Table. This approach has been taken in the community for Mirror ACL tables but not for L3 ACLs. We are extending this to L3 ACLs as well.	No
