Modify link up/down handling to use the functions from the MII
library.  Note that I track link state using the MII PHY registers
rather than the mv643xx chip's link state registers because I think
it's cleaner to use the MII library code rather than writing local
driver support code. It is also useful to make the actual MII
registers available to the user with maskable kernel printk messages
so the MII registers are being read anyway

tx_ring_skbs is actually a count of tx descriptors currently in use.
Since there may be multiple descriptors per skb, it is not the
same as the number of skbs in the ring.

Also change rx_ring_skbs to rx_desc_count to be consistent.

This patch removes the NETIF_F_HW_CSUM flag to be able to use other protocols
than IPv4. Hardware checksums for IPv4 should continue to work because

the used protocol and to not access skb->iph for non-ipv4-packets.

The Marvell mv643xx ethernet hardware requires that DMA buffers be
aligned to 8-byte boundaries.  This patch satisfies this requirement.
Buffers allocated by dev_alloc_skb() only have 4-byte alignment when
slab debugging is enabled.

Also, document that the 2-byte offset to align the IP packets on
receive is a hardware feature and is not tied to NET_IP_ALIGN.

mv643xx_eth_get_config_reg() was reading the wrong register.
mv643xx_eth_set_config_reg() was or'ing instead of setting the

mv643xx_eth_set_rx_mode() when changing to/from promiscuous mode.

mv643xx_eth_set_rx_mode().

Also, maintain promiscuous mode setting across port resets.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
