net: tftp: fix type of block arg to store_block

The block argument for store_block can be -1 when the tftp sequence
number rolls over (i.e TftpBlock == 0), so the first argument to
store_block has to be of type 'int' instead of 'unsigned'.

In our environment (gcc 4.4.5 mips toolchain), this causes incorrect
'offset' to be generated for storing the block, and the tftp block
with number 0 will be written elsewhere, resulting in a bad block in
the downloaded file and a memory corruption.

phylib: phy_startup() should return an error code on failure

phy_startup() calls the PHY driver's startup function, but it ignores the
return code from that function, and so it never returns any failures.

net: abort network initialization if the PHY driver fails

Now that phy_startup() can return an actual error code, check for that error

net/designware: Consecutive writes to the same register to be avoided

This commit is an add-on to f6c4191f. There are a few registers where
consecutive writes to the same location should be avoided or have a delay.

According to Synopsys, here is a list of the registers and bit(s) where
consecutive writes should be avoided or a delay is required:

DMA Registers:
Register 0        Bit 7
Register 6        All bits except for 24, 16-13, 2-1.

GMAC Registers:
Registers 0-3     All bits
Registers 6-7     All bits
Register 10       All bits
Register 11       All bits except for 5-6.
Registers 16-47   All bits
Register 48       All bits except for 18-16, 14.
Register 448      Bit 4.
Register 459      Bits 0-3.

net: allow setting env enetaddr from net device setting

If the net driver has setup a valid ethernet address and an ethernet
address is not set in the environment already, then set the environment
variables from the net driver setting.

This enables pxe booting on boards which don't set ethaddr env variable.

net: fec_mxc: Fix setting of RCR for xMII

At least on i.MX25, the RMII mode did not work, which is fixed by this patch.

The MII_MODE bit of the FEC RCR register means xMII, i.e. 'not 7-wire', so set
it accordingly.

According to the xMII and 7-wire (aka GPSI) standards, full duplex should be
available on xMII, but not on 7-wire, so set FCE accordingly. The FEC may
support full duplex for 7-wire too, but the reference manual does not say that,
so avoid an invalid assumption. Actually, the choice between half and full
duplex also depends on the endpoint/switch/repeater configuration, so a config
option could be added for that, but there has been no need for it so far.

net: sh_eth: add SH_ETH_TYPE_ condition

At the moment, the driver supports the following CPUs:
 - GETHER (Gigabit Ethernet) : SH7763, SH7734
 - ETHER  (Fast Ethernet)    : SH7724, SH7757

And the driver had the following "#if":

 #if defined(CONFIG_CPU_SH7763) || defined(CONFIG_CPU_SH7734)
 #if !defined(CONFIG_CPU_SH7757) && !defined(CONFIG_CPU_SH7724)
 - Those are for GETHER

 #if defined(CONFIG_CPU_SH7724) || defined(CONFIG_CPU_SH7757)
 - This is for ETHER

So, for clean up the code, this patch adds SH_ETH_TYPE_GETHER and
SH_ETH_TYPE_ETHER. And then, the patch modifies the above "#if".
