* netxen:fix napi intr enable checkAmit Kumar Salecha2009-12-081-2/+4
| | | | | | | | | | o netif_running() check for enabling interrupt at end of napi poll is not enough to cover firmwar recovery. Instead test __NX_DEV_UP bit. o Avoid re-entry into to netxen_nic_down() with __NX_DEV_UP bit check.

* netxen: fix failure cases for fw hang recoveryAmit Kumar Salecha2009-12-021-11/+15
| | | | | | | | | | | | | | | | | Handle few corner cases in firmware hang detection and recovery: o Don't mark device state as READY, till handshake with firmware is done. o During probe, if start_firmware fails, restore reference count. o Don't increment refernce count, if start_firmware fails during firmware reset. o Clear __NX_RESETTING bit, incase of fatal error or tempeature reaches critical limit so that pci remove() doesn't poll on this bit.

| * netxen : fix BOND_MODE_TLB/ALB mode.Narender Kumar2009-11-211-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | o Along with netdev->perm_addr, mac address will be maintained in device private structure. o Device limitation: We need to set mac address when ever interface comes up. In ALB/TAL mode, bonding driver calls set_mac for all slave with bond mac address. But bonding driver set netdev->dev_addr field to its original value, after enslaving interfaces. When ever active slave changes, it swap dev_addr of inactive slave with active. Yet it doesn't notify driver about change in netdev->dev_addr. As netxen driver need to set mac addr when ever interface comes up, it can't rely on netdev->dev_addr field. Specially in case of bonding mode ALB/TLB.

| | | | | | | | | | | | | | | | | | | | | | | | 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 Kumar2009-08-261-2/+82
| | | | | | | | | | | | | | | | | | | 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.
