2013-01-23ixgbe: ethtool ixgbe_diag_test cleanupJacob Keller1-12/+26
This patch cleans up the ethtool diagnostics test by ensuring that the tests work properly regardless of what state the adapter was in. The SRIOV VF check is done at the beginning, forgoing the link test. The if_running -> dev_close is moved before the link test, as well as a call to enable the Tx laser. This ensures that the link test will return valid results even when adapter was previously down. Also, a call to disable the Tx laser is added if the device was down before the start. This ensures consistent behavior of the Tx laser before and after the diagnostic checks. The end result is consistent behavior regardless of device state.

The rmb in the Tx cleanup path is a much stronger barrier than we really need. All that is really needed is a read_barrier_depends since the location of the EOP descriptor is dependent on the eop_desc value.

2013-01-19ixgbevf: Fix statistics corruptionGreg Rose1-1/+6
When the physical function (PF) is reset for any reason the statistics collection in ixgbevf_update_stats needs to wait to update until after the reset synchronization ensures that the PF driver is up and running and is finished with its own reset. Go ahead and clear the link flag to indicate this when the control message from the PF is received. The reset synchronization and recovery in the watchdog task will eventually set the link flag up when the PF has resumed.

2013-01-19ixgbe: Improve performance and reduce size of ixgbe_tx_mapAlexander Duyck1-23/+19
This change is meant to both improve the performance and reduce the size of ixgbe_tx_map. To do this I have expanded the work done in the main loop by pushing first into tx_buffer. This allows us to pull in the dma_mapping_error check, the tx_buffer value assignment, and the initial DMA value assignment to the Tx descriptor. The net result is that the function reduces in size by a little over a 100 bytes and is about 1% or 2% faster.

2013-01-19ixgbe: Update ixgbe Tx flags to improve code efficiencyAlexander Duyck3-53/+57
This change is meant to improve the efficiency of the Tx flags in ixgbe by aligning them with the values that will later be written into either the cmd_type or olinfo. By doing this we are able to reduce most of these functions to either just a simple shift followed by an or in the case of cmd_type, or an and followed by an or in the case of olinfo. To do this I also needed to change the logic and/or drop some flags. I dropped the IXGBE_TX_FLAGS_FSO and it was replaced by IXGBE_TX_FLAGS_TSO since the only place it was ever checked was in conjunction with IXGBE_TX_FLAGS_TSO. I replaced IXGBE_TX_FLAGS_TXSW with IXGBE_TX_FLAGS_CC, this way we have a clear point for what the flag is meant to do. Finally the IXGBE_TX_FLAGS_NO_IFCS was dropped since were are already carrying the data for that flag in the skb. Instead we can just check the bitflag in the skb. In order to avoid type conversion errors I also adjusted the locations where we were switching between CPU and little endian.

2013-01-19ixgbe: Make TSO check for CHECKSUM_PARTIAL to avoid skb_is_gso checkAlexander Duyck1-0/+3

Most of the time the compiler should jump ahead after failing this check to the VLAN check since in the ixgbe_tx_csum call we start with that check as well.

IEEE DCBx has a mechanism to change the default user priority.

2013-01-18igb: Add mechanism for detecting latched hardware Rx timestampMatthew Vick4-0/+51
Add a check against possible Rx timestamp freezing in the hardware via watchdog mechanism. This situation can occur when an Rx timestamp has been latched, but the packet has been dropped because the Rx ring is full. Whenever a packet comes in that should be timestamped, the Rx timestamp gets latched into the hardware registers and we will store the jiffy value in the rx_ring. The watchdog will keep track of his own jiffy timer whenever there is no valid timestamp in the registers. If the watchdog detects a valid timestamp in the registers, meaning that no Rx packet has consumed it yet, it will check which time is most recent: the last time in the watchdog or any time in the rx_rings. If the most recent "event" was more than 5 seconds ago, it will flush the Rx timestamp and print a warning message to the syslog.

2013-01-15e1000e: unexpected "Reset adapter" message when cable pulledBruce Allan2-20/+21
When there is heavy traffic and the cable is pulled, the driver must reset the adapter to flush the Tx queue in hardware. This causes the reset path to be scheduled and logs the message "Reset adapter" which could be mis- interpreted as an error by the user. Change how the reset path is invoked for this scenario by using the same method done in an existing work-around for 80003es2lan (i.e. set a flag and if the flag is set in the reset code do not log the "Reset adapter" message since the reset is expected).

2012-12-06ixgbe: check whether thermal sensor is enabled.Jacob Keller2-1/+6
The X540's internal thermal sensor should not be enabled for all devices, but only those devices which enable it in the NVM image. It is expected that actively cooled devices will have it enabled, but passively cooled devices might not want it enabled. This is due to passively cooled devices operating very near the thermal threshold, sometimes within the margin of error of the thermal sensor. Thus these devices may not be good candidates for using the thermal sensor. This patch uses the enabled bit in the FWSM register to check whether we should be enabling the thermal sensor, and only sets the THERMAL_SENSOR_CAPABLE flag for those devices which have it enabled.
