2012-03-12ixgbe: Drop unnecessary napi_schedule_prep and spare blank line from ixgbe_intrAlexander Duyck1-5/+2
This patch is a minor cleanup to address the unnecessary use of napi_schedule_prep in ixgbe_intr and to also remove a blank line that is not needed since it is separating a comment from the line it is explaining.

2012-03-12ixgbe: Default to queue pairs when number of queues is less than CPUsAlexander Duyck2-8/+8
The old code had several errors in how it was determining the vector budget. In order to simplify things this patch updates the code so that it will attempt to always allocated paired Rx/Tx vectors instead of attempting to allocate individual vectors when the number of queues is less than the number of CPUs.

2012-03-12ixgbe: Correct Adaptive Interrupt Moderation so that it will change valuesAlexander Duyck1-2/+2
This change corrects an issue in which Adaptive Interrupt Moderation was not changing values due to the fact that we were performing an and operation on the resultant value that was causing the value to never change from the default 20K interrupts per second.

2012-03-12ixgbe: Address issues with Tx WHTRESH value not being set correctlyAlexander Duyck1-2/+5
This change is meant to address the fact that the tx_itr_setting was dropping to 0 when no separate Tx vectors were provided. This had resulted in the driver incorrectly configuring the Tx ring with a WTHRESH of 1 in order to avoid Tx hangs even though that was not necessary. This change makes it so that we instead take a look at the Tx ring's q_vector to determine if the ring will have an ITR value less than 8us.

2012-03-12ixgbe: Do no clear Tx status bits since eop_desc provides enough infoAlexander Duyck1-4/+3
There isn't any need to clear the status bits in the descriptors due to the fact that the eop_desc provides enough information for us to know that we have cleaned to the last packet that the software has put on the ring. The status bits are cleared as a part of putting the frame on the ring so as long as we do not read the descriptor bit prior to reading the value eop_desc we should be able to guarantee that we will not clean beyond the end of the current data stream.

2012-03-12net: Fix issue with netdev_tx_reset_queue not resetting queue from XOFF stateAlexander Duyck1-1/+2
We are seeing dev_watchdog hangs on several drivers. I suspect this is due to the __QUEUE_STATE_STACK_XOFF bit being set prior to a reset for link change, and then not being cleared by netdev_tx_reset_queue. This change corrects that. In addition we were seeing dev_watchdog hangs on igb after running the ethtool tests. We found this to be due to the fact that the ethtool test runs the same logic as ndo_start_xmit, but we were never clearing the XOFF flag since the loopback test in ethtool does not do byte queue accounting.

2012-03-12ixgbe: remove tie between NAPI work limits and interrupt moderationJeff Kirsher1-6/+0
As noted by Ben Hutchings and David Miller, work limits for NAPI should not be tied to interrupt moderation parameters. This should be handled by NAPI, possibly through sysfs. Neil Horman & Stephen Hemminger are working on a solution for NAPI currently. In the meantime, remove this tie between work limits and interrupt moderation.

Limiting the memcpy to be the sizeof(struct rndis_message) can truncate the message if there are Per-Packet-Info or Out-of-Band data. In my earlier patch (commit 45326342), the unnecessary kmap_atomic and kunmap_atomic surrounding this memcpy have been removed because the memory in the receive buffer is always mapped. This memcpy is not necessary either. To fix the bug, I removed the memcpy. Signed-off-by: Haiyang Zhang <[email protected]> Reviewed-by: K. Y. Srinivasan <[email protected]> Signed-off-by: David S.

in iwlwifi: move setting up fw parameters Meenakshi moved code up to configure the transport layer, but this code read the sku before it was set (from the EEPROM). This killed P2P. Only the ucode_flags are needed to configure the transport layer, not the sku which _must_ be set after the EEPROM is read. We need to reconfigure the transport in case the EEPROM disabled PAN support. This is not the nicest thing to do, but we have no choice.
