* Stop unconditionally polling for RC_STATUS_PHY_RDY at the entry of
the threaded IRQ handler. Once IRQ_RX_PKT_RCVD is received we can
read immediately the packet from the buffer. However we still need
to wait afterwards for RC_STATUS_PHY_RDY, to make sure that the
ACK (in case requested) was processed and send out by the
Radio Controller, before we issue the next CMD_RC_RX.
This significantly reduces the overall time spend in the threaded
IRQ handler.
* Avoid raise condition between xmit and coincident packet reception,
by disabling the IRQ and clearing the IRQ status upon xmit entry.
* Introduce helper functions adf7242_clear_irqstat() and adf7242_cmd_rx()

READ/WRITE register and packet buffer can be done anytime as long
as SPI_READY. Only CMD transactions require RC_READY && SPI_READY.

udplite conflict is resolved by taking what 'net-next' did
which removed the backlog receive method assignment, since
it is no longer necessary.
Two entries were added to the non-priv ethtool operations
switch statement, one in 'net' and one in 'net-next, so
simple overlapping changes.

Declare the structure ieee802154_ops as const as it is only passed as an
argument to the function ieee802154_alloc_hw. This argument is of type
const struct ieee802154_ops *, so ieee80254_ops structures having this
property can be declared as const.

This driver has been sitting in the linux-zigbee[2] repository for a long
time. We updated it from time to time and made it available via our
github kernel repository. The Linux MAC802.15.4 support has improved a lot
since then. Thanks to all! So it’s finally time to upstream this driver.
The ADF7242 requires an add-on firmware for the automatic IEEE 802.15.4
operating modes. The firmware file is currently made available on the
ADF7242 wiki page here [1]
