When this is happening all other PFs are blocked on the global configuration lock. Once the package is successfully downloaded and the global configuration lock has been released then all PFs resume initialization. This includes some post package download VLAN mode configuration. To make this more obvious add the new function ice_post_pkg_dwnld_vlan_mode_cfg() so any/all post download VLAN mode configuration code can be put in here. This also makes it more clear that all PFs will call this new function.
