Implement the phys_port_name operation. Port names are pulled from the
rocker hardware model in qemu and default to the qemu name + port id.
e.g.,

sw1p1: flags=4098<BROADCAST,MULTICAST>  mtu 1500
        ether 52:54:00:12:35:01  txqueuelen 1000  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

where 'sw1' comes from the qemu command line -device rocker,name=sw1, and
'p1' is port 1.

Patch is adapted from Scott's phys_port_id patch.

Currently, if a multicast join operation fail, the vxlan interface will
be UP but not functional, without even a log message informing the user.

Now that we can grab socket lock after already having rntl, we don't
need to defer socket creation and multicast operations. By not deferring
we can do proper error reporting to the user through ip exit code.

This patch thus removes all deferred work that vxlan had and put it back
inline. Now the socket will only be created, bound and join multicast
group when one bring the interface up, and will undo all that as soon as
one put the interface down.

As vxlan_sock_hold() is not used after this patch, it was removed too.

in favor of their inner __ ones, which doesn't grab rtnl.

As these functions need to operate on a locked socket, we can't be
grabbing rtnl by then. It's too late and doing so causes reversed
locking.

So this patch:
- move rtnl handling to callers instead while already fixing some
  reversed locking situations, like on vxlan and ipvs code.
- renames __ ones to not have the __ mark:
  __ip_mc_{join,leave}_group -> ip_mc_{join,leave}_group
  __ipv6_sock_mc_{join,drop} -> ipv6_sock_mc_{join,drop}

Add the low-level device commands and definitions used for QP max-rate limiting.

This is done through the following elements:

  - read rate-limit device caps in QUERY_DEV_CAP: number of different
    rates and the min/max rates in Kbs/Mbs/Gbs units

  - enhance the QP context struct to contain rate limit units and value

  - allow to do run time rate-limit setting to QPs through the
    update-qp firmware command

  - QP rate-limiting is disallowed for VFs

The TI CC2521 is an RF power amplifier that is designed to interface
with the CC2520. Conveniently, it directly interfaces with the CC2520
and does not require any pins to be connected to a
microcontroller/processor. Adding a CC2591 increases the CC2520's range,
which is useful for border router and other wall-powered applications.

Using the CC2591 with the CC2520 requires configuring the CC2520 GPIOs
that are connected to the CC2591 to correctly set the CC2591 into TX and
RX modes. Further, TI recommends that the CC2520_TXPOWER and
CC2520_AGCCTRL1 registers are set differently to maximize the CC2591's
performance. These settings are covered in TI Application Note AN065.

This patch adds an optional `amplified` field to the cc2520 entry in the
device tree. If present, the CC2520 will be configured to operate with a
CC2591.

The expected pin mapping is:
CC2520 GPIO0 --> CC2591 EN
CC2520 GPIO5 --> CC2591 PAEN

Storing the `platform_data` struct inside of the SPI struct when using
the device tree allows for a later function to edit the content of that
struct. This patch refactors the `cc2520_get_platformat_data` function
to accept a pointer to a `cc2520_platform_data` struct and populates
the fields inside of it.

This change mirrors commit aaa1c4d2

This patch fix an issue when at86rf230_read_subreg was successful. The
function at86rf230_read_subreg will directly call regmap_read which
returns zero on successful. Nobody figured out issues yet because it was
only necessary to evaluate dvdd state while probing. This could make
trouble because the stack variable could have an random value.

The function is also used by reset the irq line before requesting irq, but
the value isn't evaluated afterwards.

MDIO controller on little endian Socs, e.g. ls2085a is similar to the
controller on big endian Socs, but the MDIO access is little endian,
we use I/O accessor function to handle endianness, so the driver can
run on little endian Socs. A property "little-endian" is used
in DTS to indicate the MDIO is little endian, if driver probes the
property, driver will access MDIO in little endian, otherwise, driver
works in big endian by default.

This patch adds a handling for calibration if we are 5 minutes in PLL
state. I first tried to implement the calibration functionality in
TX_ON state via register values CF_START and DCU_START, but this occurs
a one second delay at each calibration time.

An another solution to start a calibration is to switch from TRX_OFF
state into TX_ON, then a calibration is done automatically by
transceiver. This method will be used in this patch, after each transmit
of a frame we check with jiffies if the PLL is set 5 minutes without
doing a TRX_OFF->(TX_ON || RX_AACK_ON) or channel switch. The worst case
would be a transceiver in receiving mode only, but this is under normal
operation very unlikely.
