This commit makes use of devm_kmalloc_array() for memory allocation and the
recently introduced devm_mdiobus_alloc() API to simplify driver's code.
While here, remove a redundant out of memory error message.

The driver does not support multiple rx queues, and so it's a waste
of resources to have a default number larger than one (1).

Use eth_prepare_mac_addr_change and eth_commit_mac_addr_change, instead
of manually checking and storing the MAC address, which makes the
code slightly more robust. This fixes the lack of valid MAC address check
in the driver's .ndo_set_mac_address hook.

This commit cleans-up mvneta_init(), which initializes the hardware
and allocates the rx/qx queues. The queue allocation is simplified
by using devm_kcalloc instead of kzalloc. The unused phy_addr parameter
is removed. While here, the 'hal' references in the comments are removed.
This commit makes no functionality change.

through ip tool.
o min_tx_rate puts lower limit on the VF bandwidth. VF is guaranteed
to have a bandwidth of at least this value.
max_tx_rate puts cap on the VF bandwidth. VF can have a bandwidth
of up to this value.
o A new handler set_vf_rate for attr IFLA_VF_RATE has been introduced
which takes 4 arguments:
netdev, VF number, min_tx_rate, max_tx_rate
o ndo_set_vf_rate replaces ndo_set_vf_tx_rate handler.
o Drivers that currently implement ndo_set_vf_tx_rate should now call
ndo_set_vf_rate instead and reject attempt to set a minimum bandwidth
greater than 0 for IFLA_VF_TX_RATE when IFLA_VF_RATE is not yet
implemented by driver.
o If user enters only one of either min_tx_rate or max_tx_rate, then,
userland should read back the other value from driver and set both
for IFLA_VF_RATE.
Drivers that have not yet implemented IFLA_VF_RATE should always
return min_tx_rate as 0 when read from ip tool.
o If both IFLA_VF_TX_RATE and IFLA_VF_RATE options are specified, then
IFLA_VF_RATE should override.
o Idea is to have consistent display of rate values to user.
o Usage example: -

It was possible to call hif_stop() 2 times through
ath10k_htc_connect_init() timeout failpath which
could lead to double free_irq() kernel splat for
multiple MSI interrupt case.
Re-order init sequence to avoid this problem. The
HTC stop shouldn't stop HIF implicitly since it
doesn't implicitly start it. Since the re-ordering
required some functions to be split/removed/renamed
rename a few functions to make more sense while at
it.

ALB learning packets are currentlyalways sent using the slave mac
address for all vlans configured on top of bond. This is not always
correct, as vlans may change their mac address.
This patch introduced a concept of strict matching where the
source of learning packets can either strictly match the address
passed in, or it can determine a more correct address to use.
There are 3 casese to consider:
1) Switchover. In this case, we have a new active slave and we need
tell the switch about all addresses available on the slave.
2) Monitor. We'll periodically refresh learning info for all slaves.
In this case, we refresh all addresses for current active, and just
the slave address for other slaves.
3) Teaching of disabled adddress. This happens as part of the
failover and in this case, we alwyas to use just the address
provided.

of_set_phy_supported allows overwiting hardware capabilities of
a phy with values from the devicetree. of_set_phy_supported is
called right after phy_device_register in the assumption that
phy_probe is called from phy_device_register and the features
of the phy are already initialized. For the genphy driver this
is not true, here phy_probe is called later during phy_connect
time. phy_probe will then overwrite all settings done from
of_set_phy_supported
Fix this by moving of_set_phy_supported to the core phy code
and calling it from phy_probe.

of_set_phy_supported allows overwiting hardware capabilities of
a phy with values from the devicetree. This does not work with
the genphy driver though because the genphys config_init function
will overwrite all values adjusted by of_set_phy_supported. Fix
this by initialising the genphy features in the phy_driver struct
and in config_init just limit the features to the ones the hardware
can actually support. The resulting features are a subset of the
devicetree specified features and the hardware features.

While at it, use &pdev->dev consistently for console messages instead
of using ndev->dev for just one case and remove an unnecessary line

__team_compute_features() uses netdev_increment_features() to
combine vlan_features of slaves into vlan_features of the team.
As netdev_increment_features() only adds most features and we
start with TEAM_VLAN_FEATURES, we can end up with features none
of the slaves provided.
Initialize vlan_features only with the flags which are both in
TEAM_VLAN_FEATURES and NETIF_F_ALL_FOR_ALL. Right now there is
no such feature so that we actually initialize vlan_features
with zero but stating it explicitely will make the code more
