Fixes Rhine I cards disclosing fragments of previously transmitted frames
in new transmissions.
Before transmission, any socket buffer (skb) shorter than the ethernet
minimum length of 60 bytes was zero-padded. On Rhine I cards the data can
later be copied into an aligned transmission buffer without copying this
padding. This resulted in the transmission of the frame with the extra
bytes beyond the provided content leaking the previous contents of this
buffer on to the network.
Now zero-padding is repeated in the local aligned buffer if one is used.
Following a suggestion from the via-rhine maintainer, no attempt is made
here to avoid the duplicated effort of padding the skb if it is known that
an aligned buffer will definitely be used. This is to make the change
"obviously correct" and allow it to be applied to a stable kernel if
necessary. There is no change to the flow of control and the changes are
only to the Rhine I code path.
The patch has run on an in-service Rhine-I host without incident. Frames
shorter than 60 bytes are now correctly zero-padded when captured on a
separate host. I see no unusual stats reported by ifconfig, and no unusual
log messages.

The 40-bit DMA workaround recently implemented for 5714, 5715, and
5780 needs to be expanded because there may be other tg3 devices
behind the EPB Express to PCIX bridge in the 5780 class device.
For example, some 4-port card or mother board designs have 5704 behind
the 5714.
All devices behind the EPB require the 40-bit DMA workaround.

This patch fixes an error in the dl2k driver's DMA mapping/unmapping.
The adapter uses the upper 16bits of the DMA address for the buffer
size. However, this is not masked off when referencing the DMA
address, and can lead to errors by trying to free a DMA address out of
range.

For some reason, E1000's ->hard_start_xmit() routine returns -EFAULT
instead of one of the NETDEV_TX_* error codes. In fact, it frees up
the SKB before returning this. This makes the queueing layer think
the packet should be requeued and subsequently we corrupt a freed
object.

Add DMA workaround for chips that do not support full 64-bit DMA
addresses.
5714, 5715, and 5780 chips only support DMA addresses less than 40
bits. On 64-bit systems with IOMMU, set the dma_mask to 40-bit so
that pci_map_xxx() calls will map the DMA address below 40 bits if
necessary. On 64-bit systems without IOMMU, set the dma_mask to
64-bit and check for DMA addresses exceeding the limit in
tg3_start_xmit().
5788 only supports 32-bit DMA so need to set the mask appropriately
also.

the problem on 5714.

The axnet_cs driver can support the AMB8110 PC Card, so add the id for it.
In the old pcmcia-cs config file, this card is listed with the comment "not
specific enough". The last entry in the axnet_ids has the same comment.
They are disabled, and for good reason as it was originally identified by
the MANFID, and that is shared with several cards that use both the
pcnet_cs driver and axnet_cs driver. I tried my AMB8110 with pcnet_cs, and
found that it works fine, and I cannot find a reason for either, except
that the old config file recommended axnet_cs.

A recent patch attempted to enable more efficient memory usage by using
only 2kB descriptors for jumbo frames. The method used to implement this
has since been commented upon as "illegal" and in recent kernels even
causes a BUG when receiving ip fragments while using jumbo frames.
This patch simply goes back to the way things were. We expect some
