We still have no maintainer for e1000.
Anyone to double-check this short patch?

The values come from this enum:
enum e1000_promisc_type {
e1000_promisc_disabled = 0, /* all promisc modes disabled */
e1000_promisc_unicast = 1, /* unicast promiscuous enabled */
e1000_promisc_multicast = 2, /* multicast promiscuous enabled */
e1000_promisc_enabled = 3, /* both uni and multicast promisc */

This function disables both multicast and unicast. The PF function eth_igb_allmulticast_disable disables multicast but not unicast. I think it's better that VF and PF have the behavior.
