> Subject: [Intel-wired-lan] [PATCH net v2 1/2] ixgbe: fix bcast packets Rx on VF
> after promisc removal
>
> After a VF requested to remove the promiscuous flag on an interface, the
> broadcast packets are not received anymore. This breaks some protocols like
> ARP.
>
> In ixgbe_update_vf_xcast_mode(), we should keep the IXGBE_VMOLR_BAM
> bit (Broadcast Accept) on promiscuous removal.
>
> This flag is already set by default in ixgbe_set_vmolr() on VF reset.
