TODO: <a href="https://go.dev/issue/56539">https://go.dev/issue/56539</a>: add support for MPTCP
<p>

<!-- CL 471136, CL 471137, CL 471140 -->
On Linux, the <a href="/pkg/net/">net</a> package can now use
Multipath TCP when the kernel supports it. It is not used by
default. To use Multipath TCP when available on a client, call
the
<a href="/pkg/net/#Dialer.SetMultipathTCP"><code>Dialer.SetMultipathTCP</code></a>
method before calling the
<a href="/pkg/net/#Dialer.Dial"><code>Dialer.Dial</code></a> or
<a href="/pkg/net/#Dialer.DialContext"><code>Dialer.DialContext</code></a>
methods. To use Multipath TCP when available on a server, call
the
<a href="/pkg/net/#ListenConfig.SetMultipathTCP"><code>ListenConfig.SetMultipathTCP</code></a>
method before calling the
<a href="/pkg/net/#ListenConfig.Listen"><code>ListenConfig.Listen</code></a>
method. Specify the network as <code>"tcp"</code> or
<code>"tcp4"</code> or <code>"tcp6"</code> as usual. If
Multipath TCP is not supported by the kernel or the remote host,
the connection will silently fall back to TCP. To test whether a
particular connection is using Multipath TCP, use the
<a href="/pkg/net/#TCPConn.MultipathTCP"><code>TCPConn.MultipathTCP</code></a>
method.

In a future Go release we may enable Multipath TCP by default on
systems that support it.
