4e5e4f0d65 tg3: use the DMA state API instead of the pci equivalents
This replace the PCI DMA state API (include/linux/pci-dma.h) with the
DMA equivalents since the PCI DMA state API will be obsolete.

No functional change.

04380d401e tg3: Unify max pkt size preprocessor constants
The maximum packet size that gets programmed into the standard producer
ring control block is directly related to the packet size used to
allocate packet buffers.  This patch removes the redundant preprocessor

9dc7a11349 tg3: Re-inline VLAN tags when appropriate
The tg3 driver is written so that VLAN tagged packets can be accepted,
even if CONFIG_VLAN_8021Q or CONFIG_VLAN_8021Q_MODULE is not defined.
(Think raw interfaces.)  If the device has ASF support enabled, the
firmware requires the driver to enable VLAN tag stripping.  If VLAN
tagging is not explicitly supported by the kernel and ASF is enabled,
the driver will have to reinject the VLAN tag back into the packet
stream.

d2757fc407 tg3: Optimize rx double copy test
On a PCIX bus, the 5701 has a bug which requires the driver to double
copy all rx packets.  The rx code uses the rx_offset device member as a
flag to determine if this workaround should take effect.  The following
patch will modify the rx_offset member such that this test will become
less clear.

The patch starts by integrating the workaround check into the packet
length check.  It rounds out the implementation by relaxing the
workaround restrictions if the platform has efficient unaligned
accesses.

f0ee7acfcd gianfar: Add hardware TX timestamping support
If a packet has the skb_shared_tx->hardware flag set the device is
instructed to generate a TX timestamp and write it back to memory after
the frame is transmitted. During the clean_tx_ring operation the
timestamp will be extracted and copied into the skb_shared_hwtstamps
struct of the skb.

TX timestamping is enabled by setting the tx_type to something else
than HWTSTAMP_TX_OFF with the SIOCSHWTSTAMP ioctl command. It is only
supported by eTSEC devices.

cc772ab7cd gianfar: Add hardware RX timestamping support
The device is configured to insert hardware timestamps into all
received packets. The RX timestamps are extracted from the padding
alingment bytes during the clean_rx_ring operation and copied into the
skb_shared_hwtstamps struct of the skb. This extraction only happens if
the rx_filter was set to something else than HWTSTAMP_FILTER_NONE with
the SIOCSHWTSTAMP ioctl command.

Hardware timestamping is only supported for eTSEC devices. To indicate
device support the new FSL_GIANFAR_DEV_HAS_TIMER flag was introduced.

non-Virtex 5 platforms by adding support for accessing the Soft DMA

This patch adds support for SJA1000 based PCI CAN interface cards
from electronic system design gmbh.

Some changes have been done on the common code:
 - esd boards must not have the 2nd local interupt enabled (PLX9030/9050)
 - a new path for PLX9056/PEX8311 chips has been added
 - new plx9056 reset function has been implemented
 - struct plx_card_info got a reset function entry

In detail the following additional boards are now supported:

        CAN-PCI/200 (PCI)
        CAN-PCI/266 (PCI)
        CAN-PMC266 (PMC module)
        CAN-PCIe/2000 (PCI Express)
