1. Added support for interface and role of mesh type.
2. Enabled enable/start of mesh-point role,
   and opening and closing a connection with a mesh peer.
3. Added multirole combination of mesh and ap
   under the same limits of dual ap mode.
4. Add support for 'sta_rc_update' opcode for mesh IF.
   The 'sta_rc_update' opcode is being used in mesh_plink.c.
Add support in wlcore to handle this opcode correctly for mesh
(as opposed to current implementation that handles STA only).
5. Bumped the firmware version to support new Mesh functionality

For multiple REG Host Commands (e.g HostCmd_CMD_802_11_EEPROM_ACCESS,
HostCmd_CMD_MAC_REG_ACCESS etc.) "cpu_to_leX"-converted values are
saved to driver. So, "leX_to_cpu" conversion is required too many
times afterwards in driver.

This patch reduces the endian: conversion without saving "cpu_to_leX"
converted values in driver. This will convert endianness in prepare
command and command response path.

alloc_workqueue replaces deprecated create_singlethread_workqueue().

A dedicated workqueue has been used since the workitem viz
lp->txtimeout_reinit is involved in reinitialization if a TX timeout
occurs, which is necessary to guarantee forward progress in packet
processing. As a network device can be used during memory reclaim, the
workqueue needs forward progress guarantee under memory pressure.
WQ_MEM_RECLAIM has been set to ensure this.

Since there is only a single work item, explicit concurrency limit is
unnecessary here.

Commit d46e416c missed to update some other places which checked for
the socket being TCP-style AND Established state, as Closing state has
some overlapping with the previous understanding of Established.

Without this fix, one of the effects is that some already queued rx

teared down, and sending may also not be possible if peer initiated the
shutdown.

Also merge two if() blocks into one condition on sctp_sendmsg().

Add Hisilicon MDIO bus driver and FEMAC driver

This patch set adds a Hisilicon MDIO bus driver and
a Fast Ethernet MAC(FEMAC) driver.
We also abstract a general interface "of_phy_get_and_connect"
for PHY connect. User will have no bother with getting
"phy-mode" and "phy-handle" any more.

Changes in v1:
- Pass private data structure instead of struct mii_bus
  in MDIO read and write operation.
- Return the error which devm_clk_get() gives when MDIO probe.
- Leave the clock unprepared and disabled on error when MDIO probe.
- Abstract a general interface "of_phy_get_and_connect" for PHY connect.
- Remove the "_reset" suffixes in "reset-names" property.
- Enable tx per-packet interrupt when tx fifo full.
- Remove pointless compatible and add SoC specific compatible.
- Declare only one clock in MAC dts documentation.
- Add standard unit suffixes for "phy-reset-delays".
- Use a smaller NAPI poll weight 16 for our Fast Ethernet MAC.
- Use phy_ethtool_{get|set}_link_ksettings for ethtool ops.
- Use phydev from struct net_device in MAC driver.

TI_CPSW_PHY_SEL depended on TI_CPSW and was selected by the latter. So
there is no reason to have this symbol visible.

A further optimisation would be to put the code for both symbols into a

and simplify the module load process.

In preparation for hardware offloading of ipmr/ip6mr we need an
interface that allows to check (and later update) the age of entries.
Relying on stats alone can show activity but not actual age of the entry,
furthermore when there're tens of thousands of entries a lot of the
hardware implementations only support "hit" bits which are cleared on
read to denote that the entry was active and shouldn't be aged out,
these can then be naturally translated into age timestamp and will be
compatible with the software forwarding age. Using a lastuse entry doesn't
affect performance because the members in that cache line are written to
along with the age.
Since all new users are encouraged to use ipmr via netlink, this is
exported via the RTA_EXPIRES attribute.
Also do a minor local variable declaration style adjustment - arrange them
longest to shortest.

Some devices of the same type all export the same, random MAC address. This
behavior has been seen on the ZTE MF910, MF823 and MF831, and there are
probably more devices out there. Fix this by generating a valid random MAC
address if we read a random MAC from device.

Also, changed the memcpy() to ether_addr_copy(), as pointed out by

net: bridge: simplify receive path and consolidate forwarding paths

This set tries to simplify the receive and forwarding paths. Patch 01 is
a trivial style adjustment, patch 02 removes one conditional from the
unicast fast path, patch 03 removes another conditional and more imporantly
removes the skb0/skb2 ambiguity about locally receiving the skb and
switches to a boolean called "local_rcv".
Patch 04 is the most important change which consolidates the forwarding
paths for locally originated and forwarded packets into __br_forward. This
allows us to remove the function pointers giving a minor performance boost,
more importantly it makes it much easier to reason about the forwarding
path and reduces the code duplication that was needed when making changes.
Also it allows the receive path to fully setup the environment prior to
calling any forwarding functions (i.e. to properly set unicast, local_rcv
and search for unicast/mcast dst).
Functionally everything should stay the same after this set.

I've done basic tests with unicast/multicast/broadcast Tx/Rx. Please
review carefully.

Before this patch we had two flavors of most forwarding functions -
_forward and _deliver, the difference being that the latter are used
when the packets are locally originated. Instead of all this function
pointer passing and code duplication, we can just pass a boolean noting
that the packet was locally originated and use that to perform the
necessary checks in __br_forward. This gives a minor performance
improvement but more importantly consolidates the forwarding paths.
Also add a kernel doc comment to explain the exported br_forward()'s
arguments.

Currently if the packet is going to be received locally we set skb0 or
sometimes called skb2 variables to the original skb. This can get
confusing and also we can avoid one conditional on the fast path by
simply using a boolean and passing it around. Thanks to Roopa for the
name suggestion.
