Cause TIPC to return EAGAIN if it is unable to enable a new Ethernet
bearer because one or more recently disabled Ethernet bearers are
temporarily consuming resources during shut down.  (The previous error
code, EDQUOT, is now returned only if all available Ethernet bearer
data structures are fully enabled at the time the request to enable an
additional bearer is received.)
