This fixes a bug reported in:

http://bugzilla.kernel.org/show_bug.cgi?id=7438

tg3_close() turns off the PHY if WoL and ASF are both disabled.  On
the next tg3_open(), some devices such as the 5752M will not be
brought up correctly without a PHY reset early in the reset sequence.
The PHY clock is needed for some internal MAC blocks to function
correctly.

This problem is fixed by always resetting the PHY early in
tg3_reset_hw() when it is called from tg3_open() or tg3_resume().
tg3_setup_phy() can then be called later in the sequence without the
reset_phy parameter set to 1, since the PHY reset is already done.

Update version to 3.68.

The sky2 driver uses a single NAPI poll routine for both ports on dual ported
cards (because there is a single IRQ and status ring). Netpoll makes assumptions
about the relationship between network device and NAPI that aren't correct
on the second port, this will cause the port to never clear work.

Most systems, just have single port, so not a big issue.
The easy fix is just make the second port, not netpoll capable.

Signed-off-by: NJeff Garzik <jeff@garzik.org>

Ray Lehtiniemi reported that an incoming UDP packet flood can lock up
the ep93xx ethernet driver.  Herbert Valerio Riedel noted that due to
the way ep93xx_eth manages the RX/TXstatus rings, it cannot distinguish
a full ring from an empty one, and correctly suggested that this was
likely to be causing this lockup to occur.

Instead of looking at the hardware's RX/TXstatus ring write pointers
to determine when to stop reading from those rings, we should just check
every individual RX/TXstatus descriptor's valid bit instead, since there
is no other way to distinguish an empty ring from a full ring, and if
there is a descriptor waiting, we take the hit of reading the descriptor
from memory anyway.

This reverts commit a2b98a69.

As per Guennadi Liakhovetski, the mac address change support code breaks
some normal uses (_without_ any address changes), and until it's all
sorted out, we're better off without it.

Says Francois:

  "Go revert it.

   Despite what I claimed, I can not find a third-party confirmation by
   email that it works elsewhere.

   It would probably be enough to remove the call to
   __rtl8169_set_mac_addr() in rtl8169_hw_start() though."

Found the problem, I believe: an object lesson in the need for great
caution using ++.

Since the ++ is used as post-increment, the increment is not included
in free_index, and so the added line effectively reverts the
increment.  The produced_index side has an analagous bug.

The following change corrects this:

changes due to qe_lib changes include:

o removed inclusion of platform header file
o removed platform_device code, replaced with of_device
o removed typedefs
o uint -> u32 conversions
o removed following defines:
  QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
  BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
  because they hid sizeof/in_be32/out_be32 operations from the reader.
o removed irrelevant comments, added others to resemble removed BD_ defines
o const'd and uncasted all get_property() assignments

bugfixes, courtesy of Scott Wood, include:

- Read phy_address as a u32, not u8.
- Match on type == "network" as well as compatible == "ucc_geth", as
  device_is_compatible() will only compare up to the length of the
  test string, allowing "ucc_geth_phy" to match as well.
- fixes the MAC setting code in ucc_geth.c.  The old code was overwriting and dereferencing random stack contents.

The reason sky2 driver was locking up on transmit on the Yukon-FE chipset
is that it was misconfiguring the internal RAM buffer so the transmitter
and receiver were sharing the same space.

The code assumed there was 16K of RAM on Yukon-FE (taken from vendor driver
sk98lin which is even more f*cked up on this). Then it assigned based on that.
The giveaway was that the registers would only hold 9bits so both RX/TX
had 0..1ff for space. It is a wonder it worked at all!

This patch addresses this, and fixes an easily reproducible hang on Transmit.
Only the Yukon-FE chip is Marvell 88E803X (10/100 only) are affected.
