* drivers/net/acenic.c: fix check-after-useAdrian Bunk2007-07-24
| | | | | | | | | | | The Coverity checker noted that we've already dereferenced "dev" when we check whether it's NULL. Since it's impossible that "dev" is NULL at this place this patch removes the NULL check. Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Jeff Garzik <jeff@garzik.org>

* Fix error checking in Vitesse IRQ configAndy Fleming2007-07-24
| | | | | | | | | phy_read() returns a negative number if there's an error, but the error-checking code in the Vitesse driver's config_intr function triggers if phy_read() returns non-zero. Correct that. Signed-off-by: Andy Fleming <afleming@freescale.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

| | | | | | | | | | | | Change the threshold number of descriptors used to trigger CMB writes. The vendor reports that under certain conditions this will reduce the number of unnecessary tx interrupts and improve rx performance.

* ps3: fix rare issue that reenabling rx DMA failsMasakazu Mokuno2007-07-24
| | | | | | | | | | | | | | Fixed rare issue that 'lv1_net_start_rx_dma failed, status=-9" was shown in dmesg. This meant restarting rx DMA had been rejected by the hypervisor. This issue would caused if the guest os requested starting DMA when the hypervisor thought the DMA was in progress. The state machine for DMA status of the hypervisor would be updated by processing interrupt in the hypervisor. Thus we should wait for the interrupt delivery before restarting DMA.

| | | | | | | | | | | | | | | | gelic: TX descriptor handling cleanup - Emitted return value of NETDEV_TX_LOCKED when DMA map or kick failure. Now it would free the skb, update drop packet statistics and return OK. Requested from Jeff Garzik. - Enable tx queue if number of free descriptors are more than 2 - Fixed descriptor leak if dma map for second descriptor failed - Stopped calling xmit handler from interrupt handler in order to recheck tx queue.

| * IB/ehca: Support small QP queuesStefan Roscher2007-07-21
| | | | | | | | | | | | | | | | | | | | | | eHCA2 supports QP queues that can be as small as 512 bytes. This greatly reduces memory overhead for consumers that use lots of QPs with small queues (e.g. RDMA-only QPs). Apart from dealing with firmware, this code needs to manage bite-sized chunks of kernel pages, making sure that no kernel page is shared between different protection domains.

| | | | | | | | | | | | | | | | | | | | | | Add support for MR pages larger than 4K on eHCA2. This reduces firmware memory consumption. If enabled via the mr_largepage module parameter, the MR page size will be determined based on the MR length and the hardware capabilities -- if the MR is >= 16M, 16M pages are used, for example.

| * IB/mlx4: Fix error path in create_qp_common()Roland Dreier2007-07-21
| | | | | | | | | | | | | | | | | | | | | | | | The error handling code at err_wrid in create_qp_common() does not handle a userspace QP attached to an SRQ correctly, since it ends up in the else clause of the if statement. This means it tries to kfree() the uninitialized qp->sq.wrid and qp->rq.wrid pointers. Fix this so we only free the wrid arrays for kernel QPs. Pointed out by Michael S. Tsirkin <mst@dev.mellanox.co.il>. Signed-off-by: Roland Dreier <rolandd@cisco.com>
| * mlx4_core: Change command token on timeoutRoland Dreier2007-07-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The FW command token is currently only updated on a command completion event. This means that on command timeout, the same token will be reused for new command, which results in a mess if the timed out command *does* eventually complete. This is the same change as the patch for mthca from Michael S. Tsirkin <mst@dev.mellanox.co.il> that was just merged. It seems sensible to avoid gratuitous differences in FW command processing between mthca and mlx4. Signed-off-by: Roland Dreier <rolandd@cisco.com>

| * IB/ipath: Remove ipath_layer dead codeArthur Jones2007-07-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ipath_layer.[ch] code was an attempt to provide a single interface for the ipath verbs and ipath_ether code to use. As verbs functionality increased, the layer's functionality became insufficient and the verbs code broke away to interface directly to the driver. The failed attempt to get ipath_ether upstream was the final nail in the coffin and now it sits quietly in a dark kernel.org corner waiting for someone to notice the smell and send it along to it's final resting place.

| * | [SCSI] bsg: make class backlinksJames Bottomley2007-07-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, bsg doesn't make class backlinks (a process whereby you'd get a link to bsg in the device directory in the same way you get one for sg). This is because the bsg device is uninitialised, so the class device has nothing it can attach to. The fix is to make the bsg device point to the cdevice of the entity creating the bsg, necessitating changing the bsg_register_queue() prototype into a form that takes the generic device.
