The EFI spec indicates that get_status() should return the address of the buffer we passed into transmit to indicate the the buffer was transmitted. However we have boxes where the firmware returns some arbitrary address instead, which makes grub think that we've not sent anything. So since we have the SNP stuff opened in exclusive mode just assume any non-NULL txbuf means that our transmit occurred properly. This makes grub able to do its networking stuff properly on our broken firmware. Thanks, cc: Peter Jones <pjones@redhat.com> Signed-off-by: Josef Bacik <jbacik@fb.com>
