From 81016180e3f46f2f9ad0b62561db0793ee81227f Mon Sep 17 00:00:00 2001 From: Danielle Ratson Date: Sun, 24 Jul 2022 11:03:21 +0300 Subject: mlxsw: spectrum: Fix the shift of FID field in TX header Currently, the field FID in TX header is defined, but is not used as it is relevant only for data packets. mlxsw driver currently sends all host-generated traffic as control packets and not as data packets. 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 while adding support for PTP, some packets will be sent as data packets. Fix the wrong shift in the definition, to allow using the field later.
