[Qemu-devel] [PATCH v4 1/4] net/socket: Drop the odd 'default' case and comment

[Mao Zhongyi]

In the net_socket_fd_init(), the 'default' case and comment is odd.
If @fd really was a pty, getsockopt() would fail with ENOTSOCK. If
@fd was a socket, but neither SOCK_DGRAM nor SOCK_STREAM. It should
not be treated as if it was SOCK_STREAM.

If there is a genuine reason to support something like SOCK_RAW, it
should be explicitly handled.

So, drop the 'default' case since it is broken already.
