The new implementation changes the timeout loop implementation to avoid 1 ms
delay in each failing test. It also configures the delay to 10usec.

This patch forces the advertised capabilities during auto
negotiation to always be 10/100 Mbps and half/full as duplexing.

If AN(auto-negotiation) is ON, speed bit of control register are not
applicable. Also phy registers were not getting programmed as per the
result of AN. This patch sets only AN bit & restart AN bit for AN ON
selection & programs PHY registers as per AN result.

Phy autonegotiation works only when the ethernet cable is plugged in.
Since the phy was configured only at the init time, a plugged in cable
was necessary to initialize the phy properly.
This patch keeps a flag to check if the phy initialization has
succeeded, and calls configure_phy routine at every init if this flag
reports otherwise.

This patch solves a TX/RX problem which happens at 10Mbps, due to the
fact that we are not respecting 4 cyles of the phy_clk (2.5MHz) between
two consecutive writes on the same register.

The code assumes the phy address to be > 0, which is not true, the phy address
can be in the range 0-31.

The network controller mac resets hardware address stored in MAC_HI and MAC_LO
registers if mac is resetted. So, hw mac address needs to be restored in case
mac is explicitly resetted from driver.

Built-in Ethernet adapters support setting the mac address by means of a
ethaddr environment variable for each interface (ethaddr, eth1addr, eth2addr).
This adds similar support to the USB network side, using the names
usbethaddr, usbeth1addr, etc. They are kept separate since we don't want
a USB device taking the MAC address of a built-in device or vice versa.

When CONFIG_DW_SEARCH_PHY is disabled, the local phy_addr variable
never gets initialized which causes random behavior at runtime and a
gcc warning. So set it by default to the stored phy address.

The ctrl variable is only used when autoneg support is disabled, so only
declare it under those conditions to avoid an unused variable warning.

The include/miiphy.h header duplicates a lot of things from linux/mii.h.
So punt all the things that overlap to keep the API simple and to make
merging between U-Boot and Linux simpler.
