Commit Message

Sriharsha Basavapatna Aug. 30, 2024, 2 p.m. UTC
From: Mike Baucom <michael.baucom@broadcom.com>

Update to VFR code to:
- add the endpoint (efid) to the session
- modify the generic tables to write the l2 context id
- tfc session code changes to allow the efid to be added to the sid
- release both rfid and efid from afm

This patch includes a few related changes:

Thor2 change the counter get to clear on request
	Allow the caller to either clear on read or simply read based
	on their request.

Reject duplicate EM flow entry
	It is not necessary to add an duplicate EM entry to WC.
	This change will reject it.
