Re: [dpdk-dev] [PATCH] e1000: enable allmulticast support for VF

[Thomas Monjalon <thomas.monjalon@6wind.com>]

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 */
