sctp: remove some macro locking wrappers
In sctp.h we can find some macro locking wrappers. As Neil point out that:
"Its because in the origional implementation of the sctp protocol, there was a
user space test harness which built the kernel module for userspace execution to
cary our some unit testing on the code. It did so by redefining some of those
locking macros to user space friendly code. IIRC we haven't use those unit
tests in years, and so should be removing them, not adding them to other
locations."
So I remove them.

net: Add GRO support for UDP encapsulating protocols
This series adds GRO handlers for protocols that do UDP encapsulation, with the
intent of being able to coalesce packets which encapsulate packets belonging to
the same TCP session.
For GRO purposes, the destination UDP port takes the role of the ether type
field in the ethernet header or the next protocol in the IP header.
The UDP GRO handler will only attempt to coalesce packets whose destination
port is registered to have gro handler.
The patches done against net-next 75e4364f67 "net: stmmac: fix NULL pointer
dereference in stmmac_get_tx_hwtstamp"
Or.
v4 --> v5 changes:
- followed Eric's directives to avoid using atomic get/put ops on the
udp gro receive and complete callbacks and instead keep the rcu_read_lock
when calling the next handler on the chain.
v3 --> v4 changes:
- applied feedback from Tom on some micro-optimizations that save
branches and goto directives in the udp gro logic
- applied feedback from Eric on correct RCU programming for the
add/remove flow of the upper protocols udp gro handlers
v2 --> v3 changes:
- moved to use linked list to store the udp gro handlers, this solves the
problem of consuming 512KB of memory for the handlers.
- use a mark on the skb GRO CB data to disallow running the udp gro_receive twice
on a packet, this solves the problem of udp encapsulated packets whose inner VM
packet is udp and happen to carry a port which has registered offloads - and flush it.
- invoke the udp offload protocol registration and de-registration from the vxlan driver
in a sleepable context

These changes correct the following issues with jumbo frames on the
stmmac driver:
1) The Synopsys EMAC can be configured to support different FIFO
sizes at core configuration time. There's no way to query the
controller and know the FIFO size, so the driver needs to get this
information from the device tree in order to know how to correctly
handle MTU changes and setting up dma buffers. The default
max-frame-size is as currently used, which is the size of a jumbo
frame.
2) The driver was enabling Jumbo frames by default, but was not allocating
dma buffers of sufficient size to handle the maximum possible packet
size that could be received. This led to memory corruption since DMAs were
occurring beyond the extent of the allocated receive buffers for certain types
of network traffic.

This change adds a parameter for the Synopsys 10/100/1000
stmmac Ethernet driver to configure the maximum frame
size supported by the EMAC driver. Synopsys allows the FIFO
sizes to be configured when the cores are built for a particular
device, but do not provide a way for the driver to read
information from the device about the maximum MTU size
supported as limited by the device's FIFO size.

Some ipv6 protocols cannot handle ipv4 addresses, so we must not allow
connecting and binding to them. sendmsg logic does already check msg->name
for this but must trust already connected sockets which could be set up
for connection to ipv4 address family.
Per-socket flag ipv6only is of no use here, as it is under users control
by setsockopt.

1) In tpacket_rcv() flush dcache page we can restirct the scope
for start and end and remove one layer of indent.
2) In tpacket_destruct_skb() we can restirct the scope for ph.
3) In alloc_one_pg_vec_page() we can remove the NULL assignment

Bug Fixes for SFC driver
I am taking over the upstream patch submission work for the
sfc driver from Ben Hutchings.
These patches are bug fixes to the sfc driver involving
replacement of the PORT RESET MC command and fixing transposed
ptp_{under,over}size_sync_window_statistics
The PORT_RESET bug fix is needed for all versions supporting EF10
i.e all versions including and after 3.12.

When timestamping is enabled, stmmac_tx_clean will call
stmmac_get_tx_hwtstamp to get tx TS.
But the skb can be NULL because the last of its tx_skbuff is NULL
if this packet frame is filled in more than one descriptors.
To fix the issue, change the code:
- Store TX skb to the tx_skbuff[] of frame's last segment.
- Check skb is not NULL in stmmac_get_tx_hwtstamp.

The Allwinner A20 has an ethernet controller that seems to be
an early version of Synopsys DesignWare MAC 10/100/1000 Universal,
which is supported by the stmmac driver.
Allwinner's GMAC requires setting additional registers in the SoC's
clock control unit.
The exact version of the DWMAC IP that Allwinner uses is unknown,
thus the exact feature set is unknown.

The stmmac driver core allows passing feature flags and callbacks via

tied to compatible strings. This allows us to extend stmmac with glue

The snps,phy-addr device tree property is non-standard, and should be
removed in favor of proper phy node support. Remove it from the binding
documents and warn if the property is still used.
Most PHYs respond to address 0, but a few don't, so auto-detect PHY
address by default, to make up for the lack of explicit address selection.

The current .init and .exit callbacks requires access to driver

Though described as required, the "phy-handle" property for the DaVinci EMAC
binding is actually optional, as the driver will happily function without it,
assuming 100/FULL link; the property is not specified either in the example
device node, or in the actual EMAC device nodes for DA850 and AM3517 device
trees.

queues events can be got in all namespaces. That is because rx/tx queue
