Amit Kumar Salecha 1f5e055db3 netxen: remove sub 64-bit mem accesses
Sub 64-bit / unaligned access to oncard memory was only used
by old diagnostic tools, causes some intermittent issues when
memory controller agent is used.  The new access method was
added by commit ea6828b8aa
("netxen: improve pci memory access").  Firmware init anyway
uses 8-byte strides.

This also fixes address/offset calculation for NX2031 context
memory (SIU). For NX3031, SIU uses same register offsets
as packet memory (MIU).

Dhananjay Phadke 6a581e9398 netxen: firmware hang detection
Implement state machine to detect firmware hung state
and recover. Since firmware will be shared by all PCI
functions that have different class drivers (NIC or
FCOE or iSCSI), explicit hardware based serialization
is required for initializing firmware.

o Used global scratchpad register to maintain device
  reference count. Every probed pci function adds to
  ref count.

o Implement timer (delayed work) for each pci func
  that checks firmware heartbit every 5 sec and detaches
  itself if firmware is dead. Last detaching function
  reloads firmware. Other functions wait for firmware
  init, and re-attach themselves.

Heartbit is not supported by NX2031 firmware.

Dhananjay Phadke 67c38fc61a 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.
