* sky2: reduce default transmit ringStephen Hemminger2009-06-171-2/+2
| | | | | | | | | Reduce the size of the driver transmit ring to reduce latency and allow qdisc to do better rate control. Also make it obvious what the minimum transmit ring allowed is and why.

* sky2: receive counter updateStephen Hemminger2009-06-171-10/+19

* sky2: fix shutdown synchronizationStephen Hemminger2009-06-171-5/+9
| | | | | | | | | | | | | | The logic in sky2_down was incorrect. Receiver could report status after rx_stop was called. The steps need to be: * stop new frames from being transmitted * shut off transmit/receive logic * synchronize with NAPI to process status info about transmitter and receiver Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | Stopping all activity through ChipCmd and blindly acking the irqs is neither nice nor completely needed: the transition to low-power mode does enough work and it apparently keeps the device in a sane state.

| | | | | | | | | | | | This reverts commit 047584ce94108012288554a5f84585d792cc7f8f. This patch meshes badly with "net: Rework ucc_geth driver to use of_mdio infrastructure" (0b9da337dca972e7a4144e298ec3adb8f244d4a4).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch fixes the following bugs at http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=2005 http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=2007 If we suspend with an association and then resumed, we need to synchronize the active rxon with staging rxon, else we will get an error when iwl_alive_start try to commit rxon and staging is set to channel 0. Before going to suspend staging and active rxon are in sync. After resuming from the suspend, iwl_mac_start is called and it clears the staging rxon. Patch fixes the bug by not clearing the staging rxon in iwl_mac_start. Patch also adds similar fix to 3945.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The card firmware does not set the Command Download Ready interrupt bit when IEEE PS mode is enabled, preventing the driver from sending commands (such as the command to exit IEEE PS mode) since there is no indication that the card is ready to accept commands.

* | sky2: don't look for VPD sizeStephen Hemminger2009-06-161-15/+16
|/ | | | | | | | | | | | | | | | | | | The code to compute VPD size didn't handle some systems that use chip without VPD. Also some of the newer chips use some additional registers to store the actual size, and wasn't worth putting the additional complexity in, so just remove the code. No big loss since the code to set the VPD size was only a convenience so that utilities would not read the extra space past the end of the available VPD. Move the first PCI config read earlier to detect bad hardware where it returns all ones and refuse loading driver before furthur damage.

| | | * | IB/ehca: Remove unnecessary memory operations for userspace queue pairsStefan Roscher2009-05-135-50/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The queue map for flush completion circumvention is only used for kernel space queue pairs. This patch skips the allocation of the queue maps in case the QP is created for userspace. In addition, this patch does not iomap the galpas for kernel usage if the queue pair is only used in userspace. These changes will improve the performance of creation of userspace queue pairs.

| | | * | IB/ehca: Fall back to vmalloc() for big allocationsStefan Roscher2009-05-131-4/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In case of large queue pairs there is the possibillity of allocation failures due to memory fragmentation when using kmalloc(). To ensure the memory is allocated even if kmalloc() can not find chunks which are big enough, we fall back to allocating the memory with vmalloc().
