* RDS: Modularize RDMA and TCP transportsAndy Grover2009-08-234-16/+35
| | | | | | | | | | | Enable the building of transports as modules. Also, improve consistency of Kconfig messages in relation to other protocols, and move build dependency on IB from the RDS core code to the rds_rdma module.

* RDS: Export symbols from core RDSAndy Grover2009-08-2310-0/+29
| | | | | | | | Now that rdma and tcp transports will be modularized, we need to export a number of functions so they can call them. Signed-off-by: Andy Grover <andy.grover@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* RDS: Add TCP transport to RDSAndy Grover2009-08-238-0/+1469
| | | | | | | | | | | This code allows RDS to be tunneled over a TCP connection. RDMA operations are disabled when using TCP transport, but this frees RDS from the IB/RDMA stack dependency, and allows it to be used with standard Ethernet adapters, or in a VM.

* netxen: ethtool statistics and control for LRONarender Kumar2009-08-236-8/+114
| | | | | | | | | | | | | Add ethtool -K knob to control LRO in firmware. LRO path is completely separated from GRO, LRO packets are still fed with netif_receive_skb(). Also fix ethtool statistics to include LRO packets. Also use correct message type while configuring interrupt coalescing.

| * mwl8k: fix firmware command serialisationLennert Buytenhek2009-08-201-65/+89
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current mwl8k_priv->fw_lock spinlock doesn't actually protect against multiple commands being submitted at once, as it is not kept held over the entire firmware command submission. And since waiting for command completion sleeps, we can't use a spinlock anyway. To fix mwl8k firmware command serialisation properly, we have the following requirements: - Some commands require that the packet transmit path is idle when the command is issued. (For simplicity, we'll just quiesce the transmit path for every command.) - There are certain sequences of commands that need to be issued to the hardware sequentially, with no other intervening commands. This leads to an implementation of a "firmware lock" as a mutex that can be taken recursively, and which is taken by both the low-level command submission function (mwl8k_post_cmd) as well as any users of that function that require issuing of an atomic sequence of commands, and quiesces the transmit path whenever it's taken.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Delete most of the mwl8k_work_struct fields and options, since most of them are unused or never changed from their defaults: - We always use priv->config_wq, so delete the wqueue argument from mwl8k_queue_work(). - MWL8K_WQ_SPIN and MWL8K_WQ_POST_REQUEST are never used, as all callers sleep for request completion, so sleep unconditionally. - MWL8K_WQ_FREE_WORKSTRUCT is never used. - MWL8K_WQ_TX_WAIT_EMPTY is always set, so assume it unconditionally. - timeout_ms/txwait_attempts/tx_timeout_ms are never changed from their defaults, so just hardcode these in the workqueue worker. - step is never used.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various mwl8k_txq_xmit changes: - Extract the QoS field before adding the DMA header. - Only write to tx->status once, and only after all the other descriptor fields have been set. - Do all tx state manipulation under the tx spinlock. - Remove the priv->inconfig check, as all transmit queues will be frozen during config cycles, so we won't ever be asked to transmit if a config cycle is running. - Remove some more dead code.

| | | | | | | | | | | | | | | | | | | | | | Since firmware load commands don't generate 'command done' interrupts like normal commands do, polling for command done interrupts just unnecessarily slows down the firmware load process. Removing this bit of code speeds up loading a typical firmware image from 840 msec to 180 msec. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Signed-off-by: John W.

| * mwl8k: dma header manipulations can't failLennert Buytenhek2009-08-201-70/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adding and removing the DMA header that the mwl8k hardware requires on tx and provides on rx can never fail, since we are guaranteed to have enough headroom on the tx path to expand the packet, and we only ever shrink the packet on the rx path. (And on both paths we are guaranteed to be the only user of the skb we are handling.) This allows removing all of the skb clone handling in the tx and tx reclaim paths, and eliminates error checks in both the tx and rx paths, simplifying the code a bit more.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mwl8k_configure_filter() passes pointers to total_flags and the multicast address list to a workqueue function, while there is no guarantee that those pointers will still be valid by the time the workqueue function runs. Solve this by passing total_flags by value, and by passing an already built multicast address setup command packet to the workqueue function so that we don't have to look at the multicast address list itself outside of mwl8k_configure_filter(). Also, since ->configure_filter() can sleep now, wait synchronously for the worker to finish. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Signed-off-by: John W.
