These 4 drivers have identical full duplex flow control resolution
functions.  This patch changes them all to use one common function.

The function in question decides whether a device should enable TX and
RX flow control in a standard way (IEEE 802.3-2005 table 28B-3), so this
should also be useful for other drivers.

flags used within drivers for indicating tx and rx flow control are
defined in 4 drivers (and probably more), move these constants to mii.h.

The 3 SMSC drivers use the same constants (FLOW_CTRL_TX), but TG3 uses
TG3_FLOW_CTRL_TX, so this patch also renames the constants within TG3.

LAN9500 supports tx checksum offload, which slightly decreases cpu
utilisation.  The benefit isn't very large because we still require
the skb to be linearized, but it does save a few cycles.

This patch adds support for it, and enables it by default.

This converts pretty much everything to print_mac. There were
a few things that had conflicts which I have just dropped for
now, no harm done.

I've built an allyesconfig with this and looked at the files
that weren't built very carefully, but it's a huge patch.
