Use struct rtnl_link_stats64 as the statistics structure.

On 32-bit architectures, insert 32 bits of padding after/before each
field of struct net_device_stats to make its layout compatible with
struct rtnl_link_stats64.  Add an anonymous union in net_device; move
stats into the union and add struct rtnl_link_stats64 stats64.

Add net_device_ops::ndo_get_stats64, implementations of which will
return a pointer to struct rtnl_link_stats64.  Drivers that implement
this operation must not update the structure asynchronously.

Change dev_get_stats() to call ndo_get_stats64 if available, and to
return a pointer to struct rtnl_link_stats64.  Change callers of
dev_get_stats() accordingly.

We fix it by checking return values from all bnx2_read_phy() and proceeding

The related bnx2_enable_forced_2g5() is also fixed the same way.

If oui were a null variable then vic_provinfo_alloc() would leak memory.
But this function is only called from one place and oui is not null so
I removed the check.

I also moved the memory allocation down a line so it was easier to spot.

The point of using the devres resource management routines is that they
simplify the driver by taking care of releasing resources on failure and
release.  A recent commit added a bunch of error handling that is unnecessary
in this context.

This patch removes this redundant error handling, as well as using
dmam_alloc_coherent in place of dma_alloc_coherent in order to use this
framework consistenly throughout the driver.

Since commit cc772ab7 ("gianfar: Add
hardware RX timestamping support"), the driver no longer works on
at least MPC8313ERDB and MPC8568EMDS boards (and possibly much more
boards as well).

That's how MPC8313 Reference Manual describes RCTRL_TS_ENABLE bit:

  Timestamp incoming packets as padding bytes. PAL field is set
  to 8 if the PAL field is programmed to less than 8. Must be set
  to zero if TMR_CTRL[TE]=0.

I see that the commit above sets this bit, but it doesn't handle
TMR_CTRL. Manfred probably had this bit set by the firmware for
his boards. But obviously this isn't true for all boards in the
wild.

Also, I recall that Freescale BSPs were explicitly disabling the
timestamping because of a performance drop.

For now, the best way to deal with this is just disable the
timestamping, and later we can discuss proper device tree bindings
and implement enabling this feature via some property.

Reading the ELP_CTRL register with sdio_readb causes problems because
hardware seems to be performing a write using stuff bits in the request
(those bits contain write data in write request). This indicates that it
actually expects RAW (read after write) type of request, so perform that
when reading ELP_CTRL instead. Also cache last written value so we know
what to write when doing RAW request.

Because of the above it was not possible to wake the chip from ELP power
saving mode, PM had to be disabled to have the driver usable in SDIO
mode. After this patch PM is functional.

For backporting to 2.6.34 or earlier, this patch depends on
6c1f716e, which adds the
required SDIO funcion.

Collect all pieces concering the antenna switch table into one function.
Previously it was split up between ath5k_hw_reset() and
ath5k_hw_commit_eeprom_settings().

Also we need to set the antenna switch table when ath5k_hw_set_antenna_mode()
is called manually (by "iw phy0 antenna set", for example).

I'm not sure if we need to set the switchtable at the same place in
ath5k_hw_reset() as it was before - it is set later thru
ath5k_hw_set_antenna_mode() anyways - but i leave it there to avoid
problems(?).

Plus print switchtable registers in the debugfs file.
