> Because `ice_{set,clear}_promisc()` are now always called with the same second argument (ICE_MCAST_PROMISC_BITS), wouldn't it be better to remove the arg and instead call `ice_fltr_{clear,set}_{vlan,vsi}_vsi_promisc()` with either ICE_MCAST_VLAN_PROMISC_BITS or ICE_MCAST_PROMISC_BITS inside the function?

Because ice_{set,clear}_promisc() then could be used only for set mcast prosmisc mode so I modified them only to automatically insert ICE_PROMISC_VLAN_RX & ICE_PROMISC_VLAN_TX based on vsi->num_vlan value.

Anyway I will fix some objections from Jacob and send v2.

Thanks,
