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
constant.

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.

f89f38b8ec tg3: Unwedge stuck MSI-X vectors
The previous patch changed the code so that new rx buffer submissions to
the hardware stall if a new submission would overwrite data needed by an
unserviced rx packet.  On very busy 5717 and 57765 asic rev devices,
there is a corner case where the hardware will fail to assert an MSI-X
interrupt for rx traffic.  If that vector's interrupt never has another
reason to assert, any rx buffers held will never be serviced.  If the
buffers are never serviced and the hardware consumes all the available
rx packets for other rx rings, deadlock will result.

The most reliable and least intrusive way to work around the problem is
to detect the case where new submissions would overwrite existing data
and force all rx interrupt vectors to fire.
