link: detect buffer overflow / desync and relearn interface state
It's possible for the internal kernel buffer that reports network
events to overflow.
On Linux and NetBSD* this is handled by ENOBUFS being returned
by recv(2). On OpenBSD there is a special route(4) message RTM_DESYNC.
All other OS's don't seem to report this error, so dhcpcd cannot
detect it.
* I will commit a patch to NetBSD soon for this and will request a
pullup to NetBSD-8.
