To detect possible typos (if returning false results in an error):
else if (val[0] != "simple")
return false;

No need to block if there is a cached buffer to read.

Added "bulk mode" UDP reader. This is implemented as a separate
socket::mudpclass which usesrecvmmsgfor reading multiple packets if available.Packets are stored in a local buffer and are returned from cache. The call to the system function refills the cache.
Available only on Linux.
You need to enable it (instead of the standard UDP reader) by
--udp-mode bulkoption.
