* ixgbe: fix for 82599 erratum on Header SplittingDon Skidmore2011-02-081-2/+9
| | | | | | | | | | | | | We have found a hardware erratum on 82599 hardware that can lead to unpredictable behavior when Header Splitting mode is enabled. So we are no longer enabling this feature on affected hardware. Please see the 82599 Specification Update for more information.

| * net: remove dev_txq_stats_fold()Eric Dumazet2011-01-131-7/+16

Only remaining users are ixgbe, sch_teql, gianfar & macvlan : 1) ixgbe can be converted to use existing tx_ring counters. 2) macvlan incremented txq->tx_dropped, it can use the dev->stats.tx_dropped counter. 3) sch_teql : almost revert ab35cd4b8f42 (Use net_device internal stats) Now we have ndo_get_stats64(), use it, even for "unsigned long" fields (No need to bring back a struct net_device_stats) 4) gianfar adds a stats structure per tx queue to hold tx_bytes/tx_packets This removes a lockdep warning (and possible lockup) in rndis gadget, calling dev_get_stats() from hard IRQ context.

* | | ixgbe: update ntuple filter configurationAlexander Duyck2011-01-095-371/+250
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change fixes several issues found in ntuple filtering while I was doing the ATR refactor. Specifically I updated the masks to work correctly with the latest version of ethtool, I cleaned up the exception handling and added detailed error output when a filter is rejected, and corrected several bits that were set incorrectly in ixgbe_type.h. The previous version of this patch included a printk that was left over from me fixing the filter setup. This patch does not include that printk.

* | | ixgbe: further flow director performance optimizationsAlexander Duyck2011-01-094-44/+194
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change adds a compressed input type for atr signature hash computation. It also drops the use of the set functions when setting up the ATR input since we can then directly setup the hash input as two dwords that can be stored and passed as registers. With these changes the cost of computing the has is low enough that we can perform a hash computation on each TCP SYN flagged packet allowing us to drop the number of flow director misses considerably in tests such as netperf TCP_CRR.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When disable the Rx logic globally, we would also want to disable the per Rx queue receive logic by per queue Rx control register RXDCTL so no more DMA is happening from the packet buffer to the receive buffer associated with the Rx ring, before we start unmapping Rx ring receive buffer. The hardware may take max of 100us before the corresponding Rx queue is really disabled. Added ixgbe_disable_rx_queue() for this purpose.

* | | ixgbe: rework Tx hang detection to fix reoccurring false Tx hangsJohn Fastabend2010-11-162-79/+175
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Tx hang logic has been known to detect false hangs when the device is receiving pause frames or has delayed processing for some other reason. This patch makes the logic more robust and resolves these known issues. The old logic checked to see if the device was paused by querying the HW then the hang logic was aborted if the device was currently paused. This check was racy because the device could have been in the pause state any time up to this check. The other operation of the hang logic is to verify the Tx ring is still advancing the old logic checked the EOP timestamp. This is not sufficient to determine the ring is not advancing but only infers that it may be moving slowly. Here we add logic to track the number of completed Tx descriptors and use the adapter stats to check if any pause frames have been received since the previous Tx hang check. This way we avoid racing with the HW register and do not detect false hangs if the ring is advancing slowly. This patch is primarily the work of Jesse Brandeburg. I clean it up some and fixed the PFC checking.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change cleans up some of the items in ixgbe_map_rings_to_vectors. Specifically it merges the two for loops and drops the unnecessary vectors parameter. It also moves the vector names into the q_vectors themselves.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a number of places where we use the variable j to contain the register index of the ring. Instead of using such a non-descriptive variable name it is better that we name it reg_idx so that it is clear what the variable contains.
