BZ 516833 [1/2] netxen - P3+ updates
These patches bring the RHEL 5 driver up to parity with the upstream
driver. The first patch includes the changes up to 2.6.31, the second
patch includes the changes up to 2.6.32. These changes include bug fixes
and support for the P3+.
This work has been tested at QLogic. It applies and builds cleanly with
2.6.165.

netxen: free napi resources during detach
o Defer napi resouce allocation to device attach.
o Free napi resources and delete napi during detach.
This ensures right behavior across firmware reset.

netxen: remove netxen workqueue
o Remove private workqueue in the driver, move all
scheduled tasks to keventd workqueues. This makes
ports (interfaces) of same / different NIC boards
independent, in terms of their link watchdog and
reset tasks.
o Move quick checks for link status and temperature
in timer callback, schedule watchdog task only if
link status changed or temperature reached critical
threshold.
This also fixes deadlock when thermal panic occurs,
watchdog work was flushing workqueue that it was
sitting on.

netxen: fix coherent dma mask setting
Change default dma mask for NX3031 to 39 bit with ability
to update it to 64-bit (if firmware indicates support). Old
code was restricting it under 4GB (32-bit), sometimes causing
failure to allocate descriptor rings on heavily populated
system. NX2031 based NICs will still get 32-bit coherent mask.

netxen: fix deadlock on dev close
netxen: fix deadlock on dev close
The tx ring accounting fix in commit cb2107be43d2fc5eadec58b92b
("netxen: fix tx ring accounting") introduced intermittent
deadlock when inteface is going down.
This was possibly combined effect of speculative tx pause,
calling netif_tx_lock instead of queue lock and unclean
synchronization with napi which could end up unmasking
interrupt.

netxen: avoid frequent firmware reset
Restrict firmware reset to following cases -
o chip rev is NX2031 (firmare doesn't support heartbit).
o firmware is dead.
o previous attempt to init firmware had failed.
o we have got newer file firmware.
This speeds up module load tremendously (by upto 8 sec),
also avoids downtime for NCSI (management) pass-thru
traffic.

netxen: fix tx ring accounting
This forces every update of tx ring producer to check for
availability of space for next full TSO command. Earlier
firmware control commands didn't care to pause tx queue.
Stop the tx queue if there's not enough space to transmit one full
LSO command left on the tx ring after current transmit. This avoids
returning NETDEV_TX_BUSY after checking distance between producer
and consumer on every cpu.
Restart the tx queue only if we have cleaned up enough tx
descriptors.

netxen: add receive side scaling (rss) support
This patch enables the load balancing capability of firmware
and hardware to spray traffic into different cpus through
separate rx msix interrupts.
The feature is being enabled for NX3031, NX2031 (old) will be
enabled later. This depends on msi-x and compatibility with
msi and legacy is maintained by enabling single rx ring.

netxen: sanitize variable names
o remove max_ prefix from ring sizes, since they don't really
represent max possible sizes.
o cleanup naming of rx ring types (normal, jumbo, lro).
o simplify logic to choose rx ring size, gig ports get half
rx ring of 10 gig ports.
