-Subject: [PATCH] Workaround for unsupported socket option
-
-This is a workaround for ignoring the result of `setsockopt` call when
-given `TCP_NODELAY` as an argument. This TCP socket option is used in
-many applications (like pip and requests) for optimization purposes.
-For now, it can be safely ignored until it's supported in the kernel.
