From b093841f9ac916ce233cb59c74bf4a70a2febb2c Mon Sep 17 00:00:00 2001 From: Brett Creeley Date: Wed, 22 Jan 2020 07:21:25 -0800 Subject: [PATCH] ice: Refactor port vlan configuration for the VF Currently ice_vsi_manage_pvid() calls ice_vsi_[set|kill]_pvid_fill_ctxt() when enabling/disabling a port VLAN on a VSI respectively. These two functions have some duplication so just move their unique pieces inline in ice_vsi_manage_pvid() and then the duplicate code can be reused for both the enabling/disabling paths. Before this patch the info.pvid field was not being written correctly via ice_vsi_kill_pvid_fill_ctxt() so it was being hard coded to 0 in ice_set_vf_port_vlan(). Fix this by setting the info.pvid field to 0 before calling ice_vsi_update() in ice_vsi_manage_pvid(). We currently use vf->port_vlan_id to keep track of the port VLAN ID and QoS, which is a bit misleading. Fix this by renaming it to vf->port_vlan_info. Also change the name of the argument for ice_vsi_manage_pvid() from vid to pvid_info. In ice_vsi_manage_pvid() only save the fields that were modified in the VSI properties structure on success instead of the entire thing.
