This is an alternative way of fixing:
commit db9683fb41 ("net: phy: Make sure PHY_RESUMING state change
is always processed")
When the PHY state transitions from PHY_HALTED to PHY_RESUMING, there are
two things we need to do:
1). Re-enable interrupts (and power up the physical link, if powered down)
2). Update the PHY state and net-device based on the link status.
There's no strict reason why #1 has to be done from within the main
phy_state_machine() function. There is a risk that other changes to the
PHY (e.g. setting speed/duplex, which calls phy_start_aneg()) could cause
a subsequent state transition before phy_state_machine() has processed
the PHY_RESUMING state change. This would leave the PHY with interrupts
disabled and/or still in the BMCR_PDOWN/low-power mode.
Moving enabling the interrupts and phy_resume() into phy_start() will
guarantee this work always gets done. As the PHY is already in the HALTED
state and interrupts are disabled, it shouldn't conflict with any work
being done in phy_state_machine(). The downside of this change is that if
the PHY_RESUMING state is ever entered from anywhere else, it'll also have
to repeat this work.

This patch introduce a flag property for the wpan phy structure.
The current flag settings in ieee802154_hw are accessable in mac802154
layer only which is okay for flags which indicates MAC handling which
are done by phy. For real PHY layer settings like cca mode, transmit
power, cca energy detection level.
The difference between these flags are that the MAC handling flags are
only handled in mac802154/HardMac layer e.g. on an interface up. The phy
settings are direct netlink calls from nl802154 into the driver layer
and the nl802154 need to have a chance to check if the driver supports
this handling before sending to the next layer.
We also check now on PHY flags while dumping and setting pib attributes.
In comparing with MIB attributes the 802.15.4 gives us an default value
which we assume when a transceiver implement less functionality. In case
of MIB settings the nl802154 layer doesn't need to check on the
ieee802154_hw flags then.

MoCA interfaces require the use of an user-space daemon (mocad) which
will typically use cmd->autoneg to force the link. This is causing other
network manager applications not to get proper carrier down
notifications because of the following sequence of events:
- link down interrupt is received, link is set to 0 by the interrupt
handler
- fixed_link update callback runs and updates the BMSR register
accordingly
- PHY library polls the PHY for link status, sees the link is down,
proceeds with reporting that
- mocad gets notified of the link state and call phy_ethtool_sset()
with cmd->autoneg set to the link status (0)
- phy_start_aneg() is called at the end of phy_ethtool_sset() and sets
the PHY state to PHY_FORCING
Just make sure we notify the interface carrier appropriately when we
detect that the link is down in our fixed_link update callback. This is
made local to the bcm_sf2 driver as the PHY library does the right thing
in any case. This is similar to the GENET change introduced in
54d7c01d3e ("net: bcmgenet: enable MoCA
link state change detection").

If phy_start_aneg() was called while the phydev is in the PHY_RESUMING
state, then its state would immediately transition to PHY_AN (or
PHY_FORCING). This meant the phy_state_machine() never processed the
PHY_RESUMING state change, which meant interrupts weren't enabled for the
PHY. If the PHY used low-power mode (i.e. using BMCR_PDOWN), then the
physical link wouldn't get powered up again.
There seems no point for phy_start_aneg() to make the PHY_RESUMING -->
PHY_AN transition, as the state machine will do this anyway. I'm not sure
about the case where autoneg is disabled, as my patch will change
behaviour so that the PHY goes to PHY_NOLINK instead of PHY_FORCING. An
alternative solution would be to move the phy_config_interrupt() and
phy_resume() work out of the state machine and into phy_start().
The background behind this: we're running linux v3.16.7 and from user-space
we want to enable the eth port (i.e. do a SIOCSIFFLAGS ioctl with the
IFF_UP flag) and immediately afterward set the interface's speed/duplex.
Enabling the interface calls .ndo_open() then phy_start() and the PHY
transitions PHY_HALTED --> PHY_RESUMING. Setting the speed/duplex ends up
calling phy_ethtool_sset(), which calls phy_start_aneg() (meanwhile the
phy_state_machine() hasn't processed the PHY_RESUMING state change yet).
