Hi Andrew

As i understand it's generic problem. Maybe some BOOTP servers send
broadcast BOOTREPLY message, but it's not usually.

The FreeBSD stack option says itself:

cdl_option CYGOPT_NET_FREEBSD_STACK_ACCEPT_UNICAST {
    display "Accept unicast packets on INADDR_ANY interfaces"
    flavor  bool
    no_define
    define        BOOTP_COMPAT
    default_value 0
    description   "This option enables passing of unicast
        IP packets to the application, when the interface
        IP address is configured as INADDR_ANY (0.0.0.0).
        This option is useful for some applications that
        need to receive unicast IP packets when the interface
        address is unknown.  Such an application is bootp."
}
