From cc9c60c9edfed4fa629975848e80a45c17332b9a Mon Sep 17 00:00:00 2001 From: Jan Sokolowski Date: Wed, 9 Aug 2023 15:39:10 +0200 Subject: [PATCH] ice: refactor ice_vf_lib to make functions static As following methods are not used outside ice_vf_lib, they can be made static: ice_vf_rebuild_host_vlan_cfg ice_vf_rebuild_host_tx_rate_cfg ice_vf_set_host_trust_cfg ice_vf_rebuild_host_mac_cfg ice_vf_rebuild_aggregator_node_cfg ice_vf_rebuild_host_cfg ice_set_vf_state_qs_dis ice_vf_set_initialized In order to achieve that, the order in which these were defined was reorganized.
