f03b0ebd8e netxen: separate register and memory access lock
Since register and onboard memory access has separate
window registers, they need not be kept under same lock.

Also, memory is always accessed from process context
(mostly for firmware init and diagnostic tools).

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).

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.

fa3ce355c1 netxen: bridged mode optimizations
When the interface is put in bridged mode, destination mac
addresses are unknown to firmware. So packets take a slow
path (lower priority) in firmware reducing performance.

Firmware can cache limited number of remote unicast mac
addresses for certain interval, if "dynamic mac learning"
mode is enabled.

Driver needs to enable this "mac learning" mode in firmware.
Currently this is done through net device class sysfs entry,
possibly this can also be done upon netlink notifications to
from bridge.
