The hci_recv_stream_fragment function should have never been introduced

about the HCI transport protocol.
With all transport protocol specific detailed moved back into the

This reduces the size of hci_dev structure and also removes an exported

Pull networking fixes from David Miller:
1) In TCP, don't register an FRTO for cumulatively ACK'd data that was
previously SACK'd, from Neal Cardwell.
2) Need to hold RNL mutex in ipv4 multicast code namespace cleanup,
from Cong WANG.
3) Similarly we have to hold RNL mutex for fib_rules_unregister(), also
from Cong WANG.
4) Revert and rework netns nsid allocation fix, from Nicolas Dichtel.
5) When we encapsulate for a tunnel device, skb->sk still points to the
user socket. So this leads to cases where we retraverse the
ipv4/ipv6 output path with skb->sk being of some other address
family (f.e. AF_PACKET). This can cause things to crash since the
ipv4 output path is dereferencing an AF_PACKET socket as if it were
an ipv4 one.
The short term fix for 'net' and -stable is to elide these socket
checks once we've entered an encapsulation sequence by testing
xmit_recursion.
Longer term we have a better solution wherein we pass the tunnel's
socket down through the output paths, but that is way too invasive
for 'net' and -stable.
From Hannes Frederic Sowa.
6) l2tp_init() failure path forgets to unregister per-net ops, from
Cong WANG.

According to description in 'include/net/dsa.h', in cascade switches
configurations where there are more than one interconnected devices,
'rtable' array in 'dsa_chip_data' structure is used to indicate which
port on this switch should be used to send packets to that are destined
for corresponding switch.
However, dsa_of_setup_routing_table() fills 'rtable' with port numbers
of the _target_ switch, but not current one.
This commit removes redundant devicetree parsing and adds needed port
number as a function argument. So dsa_of_setup_routing_table() now just
looks for target switch number by parsing parent of 'link' device node.
To remove possible misunderstandings with the way of determining target
switch number, a corresponding comment was added to the source code and
to the DSA device tree bindings documentation file.
This was tested on a custom board with two Marvell 88E6095 switches with
following corresponding routing tables: { -1, 10 } and { 8, -1 }.

Commit 608cd71a9c ("tc: bpf: generalize pedit action") has added the
possibility to mangle packet data to BPF programs in the tc pipeline.
This patch adds two helpers bpf_l3_csum_replace() and bpf_l4_csum_replace()
for fixing up the protocol checksums after the packet mangling.
It also adds 'flags' argument to bpf_skb_store_bytes() helper to avoid
unnecessary checksum recomputations when BPF programs adjusting l3/l4
checksums and documents all three helpers in uapi header.
Moreover, a sample program is added to show how BPF programs can make use
of the mangle and csum helpers.

We should not consult skb->sk for output decisions in xmit recursion
levels > 0 in the stack. Otherwise local socket settings could influence
the result of e.g. tunnel encapsulation process.
ipv6 does not conform with this in three places:
1) ip6_fragment: we do consult ipv6_npinfo for frag_size
2) sk_mc_loop in ipv6 uses skb->sk and checks if we should
loop the packet back to the local socket
3) ip6_skb_dst_mtu could query the settings from the user socket and
force a wrong MTU
Furthermore:
In sk_mc_loop we could potentially land in WARN_ON(1) if we use a
PF_PACKET socket ontop of an IPv6-backed vxlan device.
Reuse xmit_recursion as we are currently only interested in protecting
tunnel devices.
