Prior to this change, most PHY configuration parameters were passed
into the STMMAC device as a separate PHY device. As well as being
unusual, this made it difficult to make changes to the MAC/PHY
relationship.
This patch moves all the PHY parameters into the MAC configuration
structure, mainly as a separate structure. This allows us to completely
ignore the MDIO bus attached to a stmmac if desired, and not create
the PHY bus. It also allows the stmmac driver to use a different PHY
from the one it is connected to, for example a fixed PHY or bit banging
PHY.
Also derive the stmmac/PHY connection type (MII/RMII etc) from the
mode can be passed into <platf>_configure_ethernet.
STLinux kernel at git://git.stlinux.com/stm/linux-sh4-2.6.32.y.git
provides several examples how to use this new infrastructure (that
actually is easier to maintain and clearer).

The patch removes the following serie of warnings
when the driver is compiled as built-in:
drivers/net/stmmac/stmmac_main.c: In function stmmac_cmdline_opt:
drivers/net/stmmac/stmmac_main.c:1855:12: warning: ignoring return
value of kstrtoul, declared with attribute warn_unused_result

Some drivers (ab)use the ethtool_ops::get_regs operation to expose
only a hardware revision ID. Commit
a77f5db361 ('ethtool: Allocate register
dump buffer with vmalloc()') had the side-effect of breaking these, as
vmalloc() returns a null pointer for size=0 whereas kmalloc() did not.
For backward-compatibility, allow zero-length dumps again.

This patch add the missing dma_unmap().
Which solved the critical issue of system freeze on heavy load.
Michal Miroslaw's rejected patch:
[PATCH v2 10/46] net: jme: convert to generic DMA API
Pointed out the issue also, thank you Michal.
But the fix was incorrect. It would unmap needed address
when low memory.
Got lots of feedback from End user and Gentoo Bugzilla.

Thank you all. :)

There are two problems:
1) "n" was allocated with alloc_skb() so we should free it with
kfree_skb() instead of regular kfree().
2) We return the freed pointer instead of NULL.
