In case of PF to alter these settings you need to change the value of the r= egister, but for VF we need to send message via mailbox. Assuming that in promiscuou= s mode we already set both allmulticast and unicast promiscuous I tried to exclude= and avoid useless messages via mailbox between PF and VF. >=20 > > + > > +static void > > +igbvf_allmulticast_disable(struct rte_eth_dev *dev) { > > + struct e1000_hw *hw =3D E1000_DEV_PRIVATE_TO_HW(dev->data- > > >dev_private); > > + > > + /* In promiscuous mode leave multicast promisc enabled */ > > + if (dev->data->promiscuous =3D=3D 0) > > + e1000_promisc_set_vf(hw, e1000_promisc_disabled); } > > + > > static int igbvf_set_vfta(struct e1000_hw *hw, uint16_t vid, bool on) = { > > struct e1000_mbx_info *mbx =3D &hw->mbx; > > -- > > 1.7.9.5
