No. ENOBUFS is a used and documented error code on Linux and SUSv2.
E.g. `man 2 send' contains:
ENOBUFS
The output queue for a network interface was full.
This generally indicates that the interface has
stopped sending, but may be caused by transient
congestion. (This cannot occur in Linux, packets
are just silently dropped when a device queue over
flows.)
