Prior this patch, the internal debugging was based on ifdef
and also some printk were useless because many info are exposed
via ethtool.
This patch remove all the ifdef defines and now we only use
netif_msg_XXX levels.

This patch tidies up the code. I have run Linden (and verified with checkpatch)
many part of the driver trying to reorganize some sections respecting the
codying-style rules in the points where it was not done.

This patch adds the minimal support to manage the PCS
modes (RGMII/SGMII) and restart the ANE.
Both TBI and RTBI are not yet supported.
Thanks to Byungho that wrote some part of this code
and tested SGMII too.
The only thing to be fixed is the get/set pause in
ethtool.

This patch starts adding in the main ISR the management of the PCS and
RGMII/SGMII core interrupts. This is to help further development
on this area. Currently the core irq handler only clears the
PCS and S-R_MII interrupts and reports the event in the ethtool stats.

This patch adds the Energy Efficient Ethernet support to the stmmac.
Please see the driver's documentation for further details about this support
in the driver.
Thanks also goes to Rayagond Kokatanur for his first implementation.
Note:
to clearly manage and expose the lpi interrupt status and eee ethtool
stats I've had to do some modifications to the driver's design and I
found really useful to move other parts of the code (e.g. mmc irq stat)
in the main directly. So this means that some core has been reworked
to introduce the EEE.
v1: initial patch
v2: fixed some sparse issues (typos)
v3: erroneously sent the v2 renamed as v3
v4:
o Fixed the return value of the stmmac_eee_init as suggested by D.Miller
o Totally reviewed the ethtool support for EEE
o Added a new internal parameter to tune the SW timer for TX LPI.
v5: do not change any eee setting in case of the stmmac_ethtool_op_set_eee fails
(it has to return -EOPNOTSUPP in that case).

This patch is to extend the number of MAC address registers
for 16 to 32. In fact, other new 16 registers are available in new
chips and this can help on perfect filter mode for unicast.
This patch also fixes the perfect filtering mode by setting the
bit 31 in the MAC address registers.
v2: fixed Coding Style.

This patch sanities the RX coe and adds the Type-1 Rx checksum offload engine (COE).
So the RX COE can be passed through the platform but can be fixed
at run-time in case of the core has the HW capability register.
Also to support the Type-1 Rx COE the driver must append the
HW checksum at the end of payload in case the Rx checksum
engine was used to offload the HW checksum.
This v2 version also fixes the IPC that has to be enabled and verified.

The Synopsys ID is now passed from the MAC core
to the main. This info will be used for managing
the HW cap register (supported in the new GMAC
generations).

DWMAC Management Counters (MMC) are not fully support.
The minimal support added in the past allowed to
only disable counters (if present) and mask their
interrupts.
This patch prepares the driver to support the MMC
removing obsolete code.

This patch removes a piece of code (actually commented)
only useful for some ST platforms in the past.
This kind of setting now can be done by using the platform
callbacks provided in linux/stmmac.h (see the stmmac.txt for
further details).

Move the STMicroelectronics driver into driver/net/ethernet/stmicro/ and
make the necessary Kconfig and Makefile changes.
