Variable Documentation

uint16_t isapnp_read_port

ISAPnP Read Port address.

ROM prefix may be able to set this address, which is why this is non-static.

struct pxe_dhcp_packet_creator pxe_dhcp_packet_creators[] [static]

Initial value:

 {
        [CACHED_INFO_DHCPDISCOVER] = { create_fakedhcpdiscover },
        [CACHED_INFO_DHCPACK] = { create_fakedhcpack },
        [CACHED_INFO_BINL] = { create_fakepxebsack },
}

PXE DHCP packet creators.
