bug: netwatch::netmon::bsd: AF_ROUTE: failed to parse rib: MessageTooShort

[jeromegn]

Describe the bug
It's unclear to me what caused this exactly, but I think it happened when my laptop went to sleep and possibly lost networking?

iroh appeared defunct after this and restarting the program fixed it.

There were panics during that time, but I have long since lost the logs.

Relevant Logs
