Comment:

 Wake-on-ARP support is not in the kernel in joyride-2263.  ("ethtool eth0"
 says "Supports: wake-on pumb" but doesn't say it supports "a".  Ditto for
 msh0.)  Comment 17 above describes how to implement it in the driver.  The
 lack of this support means that autosuspended XO's don't awaken when
 another node tries to open a connection to them (e.g. by offering to share
 something with them, or from an incoming ssh connection).
