Nice try, but this doesn't work, so I'll drop this one. The problem comes with USB network adapters (SPI would be the same). pollers get called in is_timeout() loops like USB host drivers use to poll for urb completion. So when network transfers happen and the network driver issues USB requests it can happen that in the USB host driver a poller triggers which with the periodic link check now triggers a USB request itself. barebox can't (and shouldn't) handle this reentrancy.
