From: Subbaraya Sundeep Date: Mon, 19 Feb 2024 12:55:14 +0000 (+0530) Subject: octeontx2-af: Consider the action set by PF X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3b1ae9b71c2a97f848b00fb085a2bd29bddbe8d9;p=linux.git octeontx2-af: Consider the action set by PF AF reserves MCAM entries for each PF, VF present in the system and populates the entry with DMAC and action with default RSS so that basic packet I/O works. Since PF/VF is not aware of the RSS action installed by AF, AF only fixup the actions of the rules installed by PF/VF with corresponding default RSS action. This worked well for rules installed by PF/VF for features like RX VLAN offload and DMAC filters but rules involving action like drop/forward to queue are also getting modified by AF. Hence fix it by setting the default RSS action only if requested by PF/VF.
