This allows setting a suitable write-queue max length per client. The
desired value can be different based on a lot of variables, like memory
availabilty, network and CPU load, input/output link state, etc.

Having a length of 10 packets is too low, it can be filled easily under
high load or really bursty traffic, where the input path could be polled
multiple times while the output path (write socket poll) is not called.

On (at least) Debian unstable I'm seeing the following compiler
warninig:
/usr/include/features.h:184:3: warning: #warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE" [-Wcpp]
# warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE"
Apparently this was deprecated in glibc 2.20 released in 2014 (!)

Allow to configure multiple servers and connect. Introduce a new VTY
node to allow multiple servers. Add an explicit connect. Do not put
the main connection into the same list but assume it exists.

Take out various fields into a new connection class. We will have the
option to connect to multiple servers.

Add more counters and start counting them when reading from the
PCAP library and when trying to write to the socket.

Allow to inspect UDP messages and check for GPRS, NS, BSSGP
and then filter LLC frames. Parsing the vL datastructure with
the libpcap syntax is a pain. It could be done using BPF but
we do not want to use bpf asm to specify the entire ruleset.
I looked into using libepan/libwireshark but this has memory
issues and is painful too. So let's parse UDP, NS, BSSGP using
the info we already have. I tried a bit of editcap to generate
a bit of broken data. The length check might still be bad.
I used my crash_20100602.pcap file to count the LLC frames we
detect and compare that to wireshark it ended with the right
number.
pcap add-filter gprs
can be used to enable the new filtering option after the OS
has received the packet.
