Creating a VLAN interface on top of ucc_geth adds 4 bytes
to the frame and the HW controller is not prepared to
TX a frame bigger than 1518 bytes which is 4 bytes too
small for a full VLAN frame. Add 16 bytes which will handle
the a simple VLAN and leaves 12 bytes for future expansion.

the current i.MX clock support groups together unrelated clocks
to a single clock which is then used by the driver. This can't
be accomplished with the generic clock framework so we instead
request the individual clocks in the driver. For i.MX there are
generally three different clocks:

ipg: bus clock (needed to access registers)
ahb: dma relevant clock, sometimes referred to as hclk in the datasheet
per: bit clock, pixel clock

This patch changes the driver to request the individual clocks.
Currently all clk_get will get the same clock until the SoCs
are converted to the generic clock framework

        return netif_tx_queue_stopped(txq);

and since we already have the txq in scope, we can just call that
directly in this case.

Factor out the the existing allocation and free operations
so that they can be used individually.

This is to improve code readability, and also to prepare for
possible future changes like better error recovery and more
dynamic configuration (e.g on-the-fly resizing of the rings).

This change represents a straight up relocation of the existing
code into separate routines without changing any of the contained
code itself.  Local variables are relocated as necessary.

Commit "391420f7: fec: use an unique MDIO bus name" first modified
the MDIO bus name to include the platform name, then in commit
"a7ed07d5: net: fec: correct phy_name buffer length when init phy_name"
the PHY name formatting was fixed in the case the PHY matches a PHY
driver.

The FEC driver however, also handles the case where we want to attach
to the fixed MDIO bus name, which was previously named "0", and now
"fixed-0". Change the PHY formatting logic to account for that.

When TX time stamping for PTP messages is enabled on a socket, a time
stamp is returned on the socket error queue to the user space application
after the frame was transmitted. The transmitted frame is also returned on
the error queue so that an application knows to which frame the time stamp
belongs.

In the current implementation the TxFCB is immediately followed by the
frame. Since the eTSEC inserts the TX time stamp 8 bytes after the TxFCB,
parts of the frame have been overwritten and an invalid frame was returned
on the socket error queue.

This patch fixes the described problem by adding additional 16 padding
bytes between the TxFCB and the frame for all messages sent from a time
stamping enabled socket (other sockets are not affected).

When there is not enough headroom in the skb a private copy will be made.
However, the private copy had no reference to the socket and consequently
no time stamp could be queued on the socket error queue during the
skb_tstamp_tx function. This patch fixes this issue by also stealing the
sock reference from the original skb after making the private copy.

If one only selects mx23-based boards, compile fails:

drivers/net/ethernet/freescale/fec.c:410:2: error: 'FEC_HASH_TABLE_HIGH' undeclared (first use in this function)
drivers/net/ethernet/freescale/fec.c:411:2: error: 'FEC_HASH_TABLE_LOW' undeclared (first use in this function)

This is because fec.h uses CONFIG_SOC_IMX28 to determine the register
layout of the core which makes sense since the MX23 does not have a fec.
However, Kconfig uses the broader ARCH_MXS symbol and this way even
makes the fec-driver default for MX23. Adapt Kconfig to use the more
precise SOC_IMX28 as well.
