Hi Chris,

I didn't think it was needed. In my use case I would be relying on the relevant device to be removed, (e.g. a udev notification would be received for the devices associated with the PCIe modem). ECONNRESET might also happen, with the udev events following shortly after.
Is the expectation that the client would get notified through ECONNRESET on the next sendmsg() or receive the BYE/DEL_CLIENT/DEL_SERVER control message.
Yes.
On that cleanup, I guess the client would either re-bind the socket back to 0 or wait for the mhi sysfs to come back and get the new endpoint id?
In my case I would be closing the sockets entirely. But what you describe can also be done.
