2009-09-11netxen: update copyrightDhananjay Phadke
o Add QLogic copyright, add linux-driver@qlogic.com to MAINTAINERS. o Delete old contact information. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-09-11netxen: fix tx timeout recoveryAmit Kumar Salecha
Redesign tx timeout handling in line with new firmware reset design that co-ordinates with other PCI function drivers. o For NX3031, first try to reset PCI function's own context before requesting firmware reset. o For NX2031, since firmware heartbit is not supported directly request firmware reset.

2009-09-11netxen: improve pci memory accessDhananjay Phadke
o Access on card memory through memory controller (agent) rather than moving small pci window around. Clean up the code for moving windows around. o Restrict memory accesss to 64 bit, currently only firmware download uses this.

2009-09-11netxen: change firmware write sizeAmit Kumar Salecha
Use 8 byte strides for firmware download into card memory since oncard memory controller needs 8 byte (64 bit) accesses. This avoids unnecessary rmw cycles.

2009-09-11netxen: build fix for INET=nRandy Dunlap
When CONFIG_INET is disabled, netxen has a build failure: netxen_nic_main.c:(.text+0x118fd1): undefined reference to `netxen_config_indev_addr' so make that function just an empty stub when CONFIG_INET=n.

2009-09-07netxen: firmware hang detectionDhananjay Phadke
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.

2009-08-26netxen: bridged mode optimizationsNarender Kumar
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.

2009-08-13netxen: remove netxen workqueueAmit Kumar Salecha
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.
