Sample Rate on mirror	Need ETA	Innovium	BRCM/ LinkedIn	Deferred		No	Low	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.
Sflow with remote collector	Need ETA	Innovium	BRCM/ Nvidia	Deferred		No	Low	Currently, SONiC supports sending sFlow samples to local CPU. Add support to send the samples to a remote collector  using a mirror session of type (SAI_SAMPLEPACKET_TYPE _MIRROR_SESSION).
V4/V6 L3 ACL optimization	March Need ETA	Innovium	BRCM/ LinkedIn	Deferred		No		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.
