64b9b41de8 qlge: 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.

15c052fc7f qlge: Add watchdog timer.
Add periodic heartbeat register read to trigger the eeh
recovery process.
We see cases where an eeh error was injected and the slot was
suspended.  An asic access attempt is required to flush the recovery process,
but without interrupts the process can stall.
Adding this periodic register read causes the recovery process to begin.

b2014ff8ac qlge: Get rid of 'default' rx_ring type.
Currently we have three types of RX rings.

1) Default ring - services rx_ring for broadcast/multicast, handles
firmware events, and errors.

2) TX completion ring - handles only outbound completions.

3) RSS ring - handles only inbound completions.

This patch gets rid of the default ring type and moves it's functionality
into the first RSS ring.  This makes better use of MSIX vectors since
they are a limited resource on some platforms.

b8facca01b qlge: Allow RX buf rings to be > than 4096 bytes.
RX buffer rings can be comprised of non-contiguous fixed
size chunks of memory. The ring is given to the hardware
as a pointer to a location that stores the location of
the queue.  If the queue is greater than 4096 bytes then
the hardware gets a list of said pointers.
This patch addes the necessary logic to generate the list if
the queue size exceeds 4096.

This patch removes the 0-1 dependancy and allows usage of any of the 4

determine our port number based on the comparison of the two functions:
Lower function number gets first port, higher function gets second port.

through address/data register pair.  An example would be reading

IDC 'inter-device-communication' events that require
an ACK mailbox command be sent to allow completion
