hns-mdio needs to register itself to mii-bus. The info of the device can
be read by both DT and ACPI.
HNS tries to call Linux PHY driver to help access PHY-devices, the HNS
hardware topology is as below. The MDIO controller may control several
PHY-devices, and each PHY-device connects to a MAC device. The MDIO will
be registered to mdiobus, then PHY-devices will register when each mac

New DSA bind, switches as devices
The interesting patches here are the last three. They implement a new
binding for DSA, which removes a few limitations of the current DSA
binding. In particular, it allows switches to be true Linux devices.
These devices can be on any type of bus, unlike the old DSA binding
which assumes MDIO. See the commit log for more details. The second to
last patch modifies an existing boards device tree to use the new
binding, giving a good example of how switches can be true MDIO
devices. The last patch documents the new binding.
Thanks go to Florian and Vivien for reviewing, testing and bug fixing
these patches.

The existing DSA binding has a number of limitations and problems. The
main problem is that it cannot represent a switch as a linux device,
hanging off some bus. It is limited to one CPU port. The DSA platform
device is artificial, and does not really represent hardware.

SCTP has this pecualiarity that its packets cannot be just segmented to
(P)MTU. Its chunks must be contained in IP segments, padding respected.
So we can't just generate a big skb, set gso_size to the fragmentation
point and deliver it to IP layer.
This patch takes a different approach. SCTP will now build a skb as it
would be if it was received using GRO. That is, there will be a cover
skb with protocol headers and children ones containing the actual
segments, already segmented to a way that respects SCTP RFCs.
With that, we can tell skb_segment() to just split based on frag_list,
trusting its sizes are already in accordance.
This way SCTP can benefit from GSO and instead of passing several
packets through the stack, it can pass a single large packet.
v2:
- Added support for receiving GSO frames, as requested by Dave Miller.
- Clear skb->cb if packet is GSO (otherwise it's not used by SCTP)
- Added heuristics similar to what we have in TCP for not generating
single GSO packets that fills cwnd.
v3:
- consider sctphdr size in skb_gso_transport_seglen()
- rebased due to 5c7cdf339a ("gso: Remove arbitrary checks for

This patch is a preparation for the GSO one. In order to successfully
handle GSO packets on rx path we must not call skb_linearize, otherwise
it defeats any gain GSO may have had.
This patch thus delays as much as possible the call to skb_linearize,
leaving it to sctp_inq_pop() moment. For that the sanity checks
performed now know how to deal with fragments.
One positive side-effect of this is that if the socket is backlogged it
will have the chance of doing it on backlog processing instead of
during softirq.
With this move, it's evident that a check for non-linearity in
sctp_inq_pop was ineffective and is now removed. Note that a similar
check is performed a bit below this one.

Currently we always queue a multicast packet for further processing,
even if none of the macvlan devices are subscribed to the address.
This patch optimises this by adding a global multicast filter for
a macvlan_port.
Note that this patch doesn't handle the broadcast addresses of the
individual macvlan devices correctly, if they are not all identical
to vlan->lowerdev. However, this is already broken because there
is no mechanism in place to update the individual multicast filters
when you change the broadcast address.
If someone cares enough they should fix this by collecting all
broadcast addresses for a macvlan as we do for multicast and unicast.
