stmmac DebugFS entries are currently global to the driver. As a result,
having more than one stmmac device in the system creates the following
error:
* ERROR stmmaceth, debugfs create directory failed
* stmmac_hw_setup: failed debugFS registration
This also results in being able to access the debugfs information for
the first registered device only.
This patch changes the debugfs structure to have one sub-directory per
net-device. Files under "/sys/kernel/debug/stmmaceth" will now show-up
under /sys/kernel/debug/stmmaceth/ethN/.

This file is built off of a tristate Kconfig option and also contains
modular function calls so it should explicitly include module.h to
avoid compile breakage during header shuffles done in the future.

Configure flow control correctly, and based on the receive fifo size read
as a property from the devicetree since the Synopsys stmmac fifo sizes are
configurable based on a particular chip's implementation. This patch maintains
the previous incorrect behavior unless the receive fifo size is found in the
devicetree.

Unicast pause frame detect was not being enabled for the Synopsys stmmac. This
patch sets Unicast pause frame detect in MAC register 6 so that pause frame
detection by the stmmac conforms to IEEE 802.3, Annex 31B.3.3 Receive
Operation - Specifically, a MAC shall respond to pause frames containing
either the reserved multicast address or the unique physical address
associated with this station.

An oops exists in the flow of stmmac_release().
phy_ethtool_get_wol() depends on phydev->drv.
phydev->drv will be null after stmmac_mdio_unreg() completes.
Steps to reproduce on Quark X1000:
1. ifconfig eth0 192.168.0.1
2. rmmod stmmac_pci
To fix this stmmac_mdio_unreg() should be run after unregister_netdev().

Currently we're getting IRQs after lots of resources are already
allocated:
* netdev
* clocks
* MDIO bus
Also HW gets initialized by the time when checking IRQs as well.
Now there's a possibility for master interrupt controller to be not
probed yet. This will lead to exit from GMAC probe routine with "-
EPROBE_DEFER" and so deferred probe will hapen later on.
But since we exited the first GMAC probe without release of all
allocated resources there could be conflicts on subsequent probes.
For example this is what happens for me:

This patch introduces run-time board detection through DMI and MAC-PHY
configuration function used by quark_default_data() during initialization. It
fills up the phy_addr for Galileo and Galileo Gen2 boards to indicate that the
Ethernet MAC controller is or is not connected to any PHY.
The implementation takes into consideration for future expansion in Quark
series boards that may have different PHY address that is linked to its MAC
controllers.
This piece of work is derived from Bryan O'Donoghue's initial work for Quark
X1000 enabling.

Currently, dwmac-rk uses a custom propety "phy_regulator" to get the name of the
right regulator to use to power on or power off the phy. This commit converts the
driver to use phy-supply devicetree property and the corresponding API, it cleans
the code a bit and make it simpler to maintain. This also replaces the property
phy_regulator by the standard property phy-supply in rk3288-evb-rk808.dts.

Based on Arnds review comments here https://lkml.org/lkml/2014/11/13/161,
we should not be mixing address spaces in the reg property like this driver
currently does. This patch updates the driver, dt docs and also the existing
dt nodes to pass the sysconfig offset in the syscon dt property.
This patch breaks DT compatibility! But this platform is considered WIP,
and is only used by a few developers who are upstreaming support for it.
This change has been done as a single atomic commit to ensure it is
bisectable.

Both stmmac_open() and stmmac_resume() call stmmac_hw_setup(), and
stmmac_hw_setup() call stmmac_init_ptp() unconditionally. However, only
stmmac_release() calls stmmac_release_ptp(). Since stmmac_suspend()
doesn't call stmmac_release_ptp(), stmmac_resume() also needn't call
stmmac_init_ptp().
This patch also fix a "scheduling while atomic" problem when resume
from suspend/hibernation. Because stmmac_init_ptp() will trigger
scheduling while stmmac_resume() hold a spinlock.
Callgraph of "scheduling while atomic":
stmmac_resume() --> stmmac_hw_setup() --> stmmac_init_ptp() -->
stmmac_ptp_register() --> ptp_clock_register() --> device_create() -->
device_create_groups_vargs() --> device_add() --> devtmpfs_create_node()
--> wait_for_common() --> schedule_timeout() --> __schedule()

This patch is to fix the atomicity when suspend and resume the

and the skb allocation is done out of the hw setup function and
