From 448e9cb3631ea57e4c41ea688f1689af2ed7fd60 Mon Sep 17 00:00:00 2001 From: Amit Cohen Date: Sun, 24 Jul 2022 11:03:22 +0300 Subject: mlxsw: resources: Add resource identifier for maximum number of FIDs Add a resource identifier for maximum number of FIDs so that it could be later used to query the information from firmware. In Spectrum-2 and Spectrum-3, the correction field of PTP packets which are sent as control packets is not updated at egress port. To overcome this limitation, some packets will be sent as data packets. The header should include FID, which is supposed to be 'Max FID + port - 1'. As preparation, add the required resource, to be able to query the value from firmware later. Signed-off-by: Amit Cohen Reviewed-by: Petr Machata Signed-off-by: Ido Schimmel Signed-off-by: David S.
