The patch roll back the change we made to support for the ability to
start/stop independent Tx queues within a single net device in order to
support 802.11e QoS. We need to be able to indicate to the upper layers
that packets of a given priority can not be sent any more without halting
transmission of all packets, and without rescheduling high priority packets
down to the next priority level.
So we return NETDEV_TX_BUSY in this case and rely on the stack would
take care of rescheduling... which it apparently does immediately and
consumes the CPU. This caused the ksoftirqd kernel thread consuming almost
all the CPU...
To put the code back to the way it was before we made these changes we
put the call netif_queue_stop back in ipw_tx_skb. This effectively
disables multiple priority based transmit queues for 802.11e, but given
that its broken anyway...

As stated in a comment, the ipw2200 driver uses several routines that
were borrowed from ieee80211_geo.c. As ipw2200 requires ieee80211,
these routines are duplicated. The attached patch, which is sent
as an attachment to preserve whitespace, converts ipw2200.c to use
the ieee80211 versions, thereby reducing bloat in both the source
and binary.

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.
Thanks,

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.

As documented in National application note 1287 the RX state machine on
the natsemi chip can lock up under some conditions (mostly related to
heavy load). When this happens a series of bogus packets are reported
by the chip including some oversized frames prior to the final lockup.
This patch implements the fix from the application note: when an
oversized packet is reported it resets the RX state machine, dropping
any currently pending packets.

This patch converts the natsemi driver to use NAPI. It was originally
based on one written by Harald Welte, though it has since been modified
quite a bit, most extensively in order to remove the ability to disable
NAPI since none of the other drivers seem to provide that functionality
any more.

Originally submitted by Kenzo Iwami; his original description is:
The current bonding driver receives duplicate packets when broadcast/
multicast packets are sent by other devices or packets are flooded by the
switch. In this patch, new flags are added in priv_flags of net_device
structure to let the bonding driver discard duplicate packets in
dev.c:skb_bond().
Modified by Jay Vosburgh to change a define name, update some
comments, rearrange the new skb_bond() for clarity, clear all bonding
priv_flags on slave release, and update the driver version.
