This patch is to kill directly reference of netdev->priv too.
Because the private data needs special memory: lower 16MB DMA.
alloc_etherdev() can not do this work.
So we can't use netdev->priv to point to netdev's private data.
Use netdev->ml_priv instead.

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.

Currently, if multiple unicast addresses are programmed into a
mv643xx_eth interface, the core networking will resort to enabling
promiscuous mode on the interface, as mv643xx_eth does not implement
->set_rx_mode().
This patch switches mv643xx_eth over from ->set_multicast_list()
to ->set_rx_mode(), and implements support for secondary unicast
addresses. The hardware can handle multiple unicast addresses as
long as their first 11 nibbles are the same (i.e. are of the form
xx:xx:xx:xx:xx:xy where the x part is the same for all addresses), so
if that is the case, we use that mode. If it's not the case, we enable
unicast promiscuous mode in the hardware, which is slightly better than
enabling promiscuous mode for multicasts as well, which is what would
happen before.
While we are at it, change the programming sequence so that we
don't clear all filter bits first, so we don't lose all incoming
packets while the filter is being reprogrammed.

The mv643xx_eth driver uses the rdl()/wrl() macros to read and
write hardware registers. Per-port registers are accessed in the
following way:
#define PORT_STATUS(p) (0x0444 + ((p) << 10))
[...]
static inline u32 rdl(struct mv643xx_eth_private *mp, int offset)
{
return readl(mp->shared->base + offset);
}
[...]
port_status = rdl(mp, PORT_STATUS(mp->port_num));
By giving the per-port 'struct mv643xx_eth_private' its own
'void __iomem *base' pointer that points to the per-port register
area, we can get rid of both the double indirection and the << 10
that is done for every per-port register access -- this patch does
that.

When suspending the device the ring structure is freed which causes it to
loose track of the count. To resolve this we need to move the ring count
outside of the ring structure and store it in the adapter struct.
In addition to resolving the suspend/resume issue this patch also addresses
issues seen in the event of memory allocation errors causing uneven ring
sizes on multiple queues.
