* | netxen: add hardware LRO supportDhananjay Phadke2009-08-051-22/+102
| | | | | | | | | | | | | | | | | | | | | | | | | | Add support to handle aggregate packets from firmware. Local TCP flows are automatically identified by firmware based on the dest IP hash added by driver for local IP addresses. The packets are sent down on the jumbo rx ring.

| * netxen: reset ring consumer during cleanupDhananjay Phadke2009-07-261-0/+7
| | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | o remove superfluous code to setup PCI dma watchdog for NX2031. o disable dma watchdog completely for NX3031 (not required). Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* | netxen: enable ip addr hashingDhananjay Phadke2009-07-271-25/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | NX3031 hardware requires local IP addresses for packet accumulation (LRO). IP address hashing is required to distinguish a local TCP flow from others (forwarded or guest). This patch adds listener for IP and netdev events and configures IP address in the firmware.

* netxen: fix deadlock on dev closeDhananjay Phadke2009-07-201-2/+3
| | | | | | | | | | | | | | | | 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 Phadke2009-07-021-8/+78
| | | | | | | | | | | | | | | | 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.

* netxen: fix the version code macroDhananjay Phadke2009-07-021-11/+14
| | | | | | | | | | | | | 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.

* netxen: fix firmware init handshakeDhananjay Phadke2009-06-231-17/+20
| | | | | | | | | | | | 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.

* netxen: fix tx ring accountingDhananjay Phadke2009-06-181-6/+5
| | | | | | | | | | | | | | | | | 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.

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.

| | | | | | | | | | | | | The generic packet receive code takes care of setting netdev->last_rx when necessary, for the sake of the bonding ARP monitor. Drivers need not do it any more.

| | | | | | | | | | | | | For NX3031, multicast filtering, promisc mode, and max frame size setting is handled by firmware, driver needs to send request to enable/disable it.

* netxen: cut-through rx changesDhananjay Phadke2008-07-221-61/+130
| | | | | | | | | | | | | | | NX3031 supports cut-through operation where ingress packets are directly dma'ed into host buffers to reduce latency. This requires larger dma buffers (2kb) and different alignemnt. The buffer posting logic is changed a bit. The free rx buffers are maintained in linked list, since the received reference handles can be out of order. However rx descriptors are still posted sequentially, indexed by producer.
