tcp: IPv6 support for fastopen server

This patch series add IPv6 support for fastopen server. To minimize
code duplication in IPv4 and IPv6, the current v4 only code is
refactored and common code is moved into net/ipv4/tcp_fastopen.c.

Also the current code uses a different function from
tcp_v4_send_synack() to send the first SYN-ACK in fastopen.
The new code eliminates this separate function by refactoring the
child-socket and syn-ack creation code.  After these refactoring
in the first four patches, we can easily add the fastopen code in
IPv6 by changing corresponding IPv6 functions.

Note Fast Open client already supports IPv6. This patch is for
the server-side (passive open) IPv6 support only.

After all the preparatory works, supporting IPv6 in Fast Open is now easy.
We pretty much just mirror v4 code. The only difference is how we
generate the Fast Open cookie for IPv6 sockets. Since Fast Open cookie
is 128 bits and we use AES 128, we use CBC-MAC to encrypt both the
source and destination IPv6 addresses since the cookie is a MAC tag.

If a fast open socket is already accepted by the user, it should
be treated like a connected socket to record the ICMP error in
sk_softerr, so the user can fetch it. Do that in both tcp_v4_err
and tcp_v6_err.

Also refactor the sequence window check to improve readability
(e.g., there were two local variables named 'req').

To avoid large code duplication in IPv6, we need to first simplify
the complicate SYN-ACK sending code in tcp_v4_conn_request().

To use tcp_v4(6)_send_synack() to send all SYN-ACKs, we need to
initialize the mini socket's receive window before trying to
create the child socket and/or building the SYN-ACK packet. So we move
that initialization from tcp_make_synack() to tcp_v4_conn_request()
as a new function tcp_openreq_init_req_rwin().

After this refactoring the SYN-ACK sending code is simpler and easier
to implement Fast Open for IPv6.

cdc_mbim: cleanups and new features

This series depends on commit 6b5eeb7f ("net: cdc_mbim: handle
unaccelerated VLAN tagged frames"), which is currently in "net" but
not yet in "net-next".

Patch 4 might have a minor context collision with the "cdc_ncm: add
buffer tuning and stats using ethtool" series I just posted for
review.  Please let me know if I should submit an adjusted version
in either direction.  These two series' are otherwise completely
independent of each other.

The major new feature here is in patch 1, which I hope will solve
some problems with the original design without changing the existing
API, optionally allowing IP session 0 to be treated like any other
MBIM session.

The rest are some minor cleanups and finally some documentation of
the current driver APIs, after this series has been applied.  I
started feeling a bit more mortal than usual lately, which probably
is healthy, and realized that I should put some of the stuff in my
head in a somewhat less volatile storage.

v2:

Fixed patch 1 so that it actually does what it claims to do. This time
it is even tested for functionality, and not just build tested...
====================

The NCM class match in the cdc_mbim driver is confusing and
cause unexpected behaviour. The USB core guarantees that a
USB interface is in altsetting 0 when probing starts. This
means that devices implementing a NCM 1.0 backwards
compatible MBIM function (a "NCM/MBIM function") always hit
the NCM entry in the cdc_mbim driver match table. Such
functions will never match any of the MBIM entries.

This causes unexpeced behaviour for cases where the NCM and
MBIM entries are differet, which is currently the case for
all except Ericsson devices.

Improve the probing of NCM/MBIM functions by looking up the
device again in the cdc_mbim match table after switching to
the MBIM identity.

The shared altsetting selection is updated to better
accommodate the new probing logic, returning the preferred
altsetting for the control interface instead of the data
interface. The control interface altsetting update is moved
to the cdc_mbim driver. It is never necessary to change the
control interface altsetting for NCM.

DSS VLANs are pseudo network interfaces representing arbitrary
data streams, and specifically not IP. Preventing spurious IP
packets can sometimes be a hassle. The kernel will for example
send an IPv6 Router Solicit when the interface is brought up
unless the user has been careful enough to disable IPv6 first.
Such packets forwared to a MBIM DSS session will look like
spurious noise to the device, and can cause it to log an error
or even malfunction.

Drop all IP packets on the designated DSS VLANs to prevent such
unwanted spurious transmissions.

The cdc_mbim driver maps 802.1q VLANs to MBIM IP and DSS
sessions. MBIM IP session 0 is handled as an exception and
is mapped to untagged frames.

This patch adds optional support for remapping MBIM IP
session 0 to 802.1q VLAN ID 4094 instead. The default
behaviour is not changed. The new behaviour is triggered
by adding a link for this previously unsupported VLAN.

The untagged mapping was chosen initially to support the
assumed most common use case: Most current MBIM devices only
support a single IP session (i.e. session 0 only), and using
untagged frames lets the users completely ignore the
additonal complexity of the multiplexing layer.

But when the multiplexing features of MBIM are used, then
this netdev gets a double meaning: It becomes the master
interface for all the VLAN subdevs the additional sessions
are mapped to, while still serving as the untagged IP
interface for session 0.

This can be problematic, especially when using Device Service
Streams (DSS), as have become apparent recently with the
availability of devices with real DSS support. Some use cases
need to e.g set a MTU which is higher than allowed for IP
Session 0. The dual role also leads to the situation where
the IP Session 0 interface cannot be taken down without
breaking unrelated IP or DSS sessions - a devastating side
effect which applications managing a simple IP session cannot
be expected to be aware of. A typical DHCP client will assume
that it should bring the interface down after releasing the
IP lease.

These problems can be avoided by tagging IP session 0 packets
too, making this session similar to all other multiplexed
sessions. This redefines the main netdev as an upper master
interface only.
