This patch makes the EMAC driver use the new DCR access methods. It
doesn't yet uses dcr_map() and thus still only work with real DCRs.
This will be fixed in a later patch

This fixes the problem of not receiving packets in the Xen bridging
environment. The Xen script sets the device's MAC address to
FE:FF:FF:FF:FF:FF and puts the device in promiscuous mode. The
firmware had problem receiving all packets in this configuration.
New firmware and setting the PROM_VLAN bit when in promiscuous mode
will fix this problem.

The beast had a long and not very happy history. At one
point, a friend (netdump) had asked that he open up a little.
Well, the friend was long gone now, and the beast had
this dangling piece hanging (netpoll_queue).
It wasn't hard to stitch the netpoll_queue back in
where it belonged and make everything tidy.

The beast was not always healthy. When it was sick,
it tended to be laconic and not tell anyone the real problem.
A few small changes had it telling the world about its
problems, if they really wanted to hear.

Most PHYs connect to an ethernet controller over a GMII or MII
interface. However, a growing number are connected over
different interfaces, such as RGMII or SGMII.
The ethernet driver will tell the PHY what type of connection it
is by setting it manually, or passing it in through phy_connect
(or phy_attach).
Changes include:
* Updates to documentation
* Updates to PHY Lib consumers
* Changes to PHY Lib to add interface support
* Some minor changes to whitespace in phy.h
* gianfar driver now detects interface and passes appropriate
value to PHY Lib

If transmit lock is contended on, then push return code back
and retry at higher level.
Bugfix: If buffer is reallocated because of lack of headroom
and the send is blocked, then drop packet. This is necessary
because caller would end up requeuing a freed skb.

It is possible for the sky2 driver NAPI poll routine to be called with
IRQ's disabled if netpoll is trying to make space in the tx queue. This
is an obscure path, but if it happens, the kfree_skb needs to happen
via softirq. Calling kfree_skb with IRQ's disabled is a not allowed.
