Subject: [PATCH net-next 0/4] mlxsw: Add SIP and DIP mangling support

Danielle says:

On Spectrum-2 onwards, it is possible to overwrite SIP and DIP address
of an IPv4 or IPv6 packet in the ACL engine. That corresponds to pedit
munges of, respectively, ip src and ip dst fields, and likewise for ip6.
Offload these munges on the systems where they are supported.

Patchset overview:
Patch #1: introduces SIP_DIP_ACTION and its fields.
Patch #2-#3: adds the new pedit fields, and dispatches on them on
	     Spectrum-2 and above.
Patch #4 adds a selftest.

Danielle Ratson (4):
  mlxsw: core_acl_flex_actions: Add SIP_DIP_ACTION
  mlxsw: Support FLOW_ACTION_MANGLE for SIP and DIP IPv4 addresses
  mlxsw: Support FLOW_ACTION_MANGLE for SIP and DIP IPv6 addresses
  selftests: forwarding: Add a test for pedit munge SIP and DIP
