[PATCH v4 0/2] net: tap: check file descriptor can be used

[Laurent Vivier <lvivier@redhat.com>]

v4: use qemu_try_set_nonblock() with vhostfd in net_init_tap_one(),
    and with fd in net_init_socket()

v3: move qemu_fd_is_valid() checking into a new function
    qemu_try_set_nonblock(), and use qemu_try_set_nonblock() in
    qemu_set_nonblock().

v2: Add patch from Daniel to check the fd can be used

    I have updated Daniel's patch not to check for EINVAL on TUNGETIFF
    as I think we can avoid this special case because TUNGETIFF
    is available since kernel v2.6.27 (October 2008)
    Moreover I think the code was wrong as it was checking with -EINVAL and
    not EINVAL.
