This patch contains two fixes.  The first fix is to the tx and rx descriptor rings clean up process.  The second fix is to jumbo frames, which cleans up the code logic and removes most of the fifo related limitations on jumbo frames.  This is because the driver code now supports splitting a packet across multiple descriptors.

first, in order to support old SLOF releases and to allow

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
NETIF_F_IP_CSUM is still set.  The sanity-check has been enhanced to check
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.
