We don't get a "I failed to transmit this" bit from the firmware,
so we must work around this my comparing the retries count to
the maximum possible retry count.
Of course, that's not an ideal solution. Especially because I think
When it succeed on the exact last retry, we take it as failure.
Though, that's very unlikely it fails 7 times give or take and then
suddenly succeeds.
