* netxen: fix tx timeout recoveryAmit Kumar Salecha2009-09-11
| | | | | | | | | | | | | | | | 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.

* netxen: improve pci memory accessDhananjay Phadke2009-09-11
| | | | | | | | | | | | 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.

* netxen: firmware hang detectionDhananjay Phadke2009-09-07
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* netxen: bridged mode optimizationsNarender Kumar2009-08-26
| | | | | | | | | | | | | | | | | | | 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.

* netxen: fix deadlock on dev closeDhananjay Phadke2009-07-20
| | | | | | | | | | | | | | | | 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 resetDhananjay Phadke2009-07-02

* netxen: fix tx ring accountingDhananjay Phadke2009-06-18
| | | | | | | | | | | | | | | | | 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.
