From: Martin Elshuber <martin.elshuber@theobroma-systems.com>

libwebsockets allows the usage of unix-domain-sockets since 2016,
so add an option to enable its usage.

We like to have an else clause that explicitly disable the option:

    else
    LIBWEBSOCKETS_CONF_OPTS += -DLWS_UNIX_SOCK=OFF
    endif

Indeed the default value may change when the version is bumped, which is
actually what hapenned with this option between 3.2.2 (currently in
Buildroot), and what they currently have in master (commit 911898ad7).

However, in this case, an option is not even needed: the size increase
is a mere 12 bytes:

    $ ls -l output-nosock/target/usr/lib/libwebsockets.so.15
    -rwxr-xr-x 1 ymorin ymorin 183292 Jun 14 10:13 output-nosock/target/usr/lib/libwebsockets.so.15

    $ ls -l output-sock/target/usr/lib/libwebsockets.so.15
    -rwxr-xr-x 1 ymorin ymorin 183304 Jun 14 10:15 output-sock/target/usr/lib/libwebsockets.so.15

So this does not even warrant an option to start with.

Applied with the option removed, thanks.

Regards,
Yann E. MORIN.
