[Spice-devel] [PATCH spice] server: Don't complain if setsockopt NODELAY fails on unix sockets

[Hans de Goede]

With Daniel P. Berrange's patches to allow use of pre-supplied fd's
as channels, we can no longer be sure that our connections are TCP
sockets, so it makes no sense to complain if a TCP/IP specific
setsockopt fails with an errno of ENOTSUP.

Note that this extends Daniel's commit 492ddb5d1d595e2d12208f4602b18e4432f4e6b4
which already added the same check to server/inputs_channel.c
