2009-08-13netxen: free napi resources during detachDhananjay Phadke
o Defer napi resouce allocation to device attach. o Free napi resources and delete napi during detach. This ensures right behavior across firmware reset. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: David S. Miller <davem@davemloft.net>
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.

2009-08-05netxen: fix dma mask update calculationDhananjay Phadke
Fix dma mask calculation that caps at 63-bit addressing even when firmware advertises full 64-bit support. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-08-02netxen: fix coherent dma mask settingDhananjay Phadke
Change default dma mask for NX3031 to 39 bit with ability to update it to 64-bit (if firmware indicates support). Old code was restricting it under 4GB (32-bit), sometimes causing failure to allocate descriptor rings on heavily populated system. NX2031 based NICs will still get 32-bit coherent mask.

2009-07-26netxen: reset ring consumer during cleanupDhananjay Phadke
Reset consumer of status rings to 0 when cleaning up sw resources. Status rings are not deleted during suspend since they have napi objects. This ensures correct rx processing across suspen-resume.

2009-07-20netxen: fix thermal check and shutdownDhananjay Phadke
Check temperature for all PCI functions, that can allow graceful shutdown of all interfaces on the overheated card. Old code was only monitoring temperature for function 0 only. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-07-20netxen: fix deadlock on dev closeDhananjay Phadke
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.

2009-07-20netxen: fix context deletion sequenceDhananjay Phadke
o Use D3 reset context deletion for NX2031, it cleans up more resources in the firmware. o Release rx buffers after hardware context has been reset. o Delete tx context after rx context, some firmware control commands are sent on tx context, so it should be the last to go. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-07-02netxen: avoid frequent firmware resetDhananjay Phadke
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. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-07-02netxen: fix the version code macroDhananjay Phadke
Correct firmware encoding is 8 bit major, 8 bit minor and 16 bit subversion. Flash has sizes rightly set, but original driver submission messed it leaving 16 bit major and 8 bit subversion. Also fix a infinite loop when cut-thru file firmware is invalid. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-06-23netxen: fix firmware init handshakeDhananjay Phadke
Make sure all functions run firmware init handshake. If PCI function 0 fails to initialize firmware, mark the state failed so that other functions on the same board bail out quickly instead of waiting 30s for firmware handshake.

2009-06-18netxen: fix tx ring accountingDhananjay Phadke
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.

2009-06-18netxen: fix detection of cut-thru firmware modeDhananjay Phadke

2009-05-29net: dont update dev->trans_start in 10GB driversEric Dumazet
Followup of commits 9d21493b4beb8f918ba248032fefa393074a5e2b and 08baf561083bc27a953aa087dd8a664bb2b88e8e (net: tx scalability works : trans_start) (net: txq_trans_update() helper) Now that core network takes care of trans_start updates, dont do it in drivers themselves, if possible. Multi queue drivers can avoid one cache miss (on dev->trans_start) in their start_xmit() handler.

This patch enables the load balancing capability of firmware and hardware to spray traffic into different cpus through separate rx msix interrupts. The feature is being enabled for NX3031, NX2031 (old) will be enabled later. This depends on msi-x and compatibility with msi and legacy is maintained by enabling single rx ring.
