    ice(4): Handle allmulti flag in ice_if_promisc_set function
    
    In the ice_if_promisc_set function, the driver currently disables the
    IFF_ALLMULTI flag, thereby preventing the activation of multicast mode.
    To address this issue, implement appropriate handling to ensure the
    flag is managed correctly.
