From fc51de96ed2f7fcefb99991200aac6710b769eba Mon Sep 17 00:00:00 2001 From: Neerav Parikh Date: Tue, 24 Feb 2015 06:58:53 +0000 Subject: [PATCH] i40e: Only enable TC0 for NIC partition type In case of MFP mode the driver was returning incorrect number of TCs for partitions that are not enabled for iSCSI. Though the driver does not configure these TCs in the Tx scheduler for the NIC partitions; it does use this map to setup the queue mappings. This patch fixes this and keeps all the NIC partitions to the default PF TC i.e. TC0.
