rt2800 already reports the tx ack status of each frame back to mac80211. Advertise this by setting IEEE80211_HW_REPORTS_TX_ACK_STATUS for rt2800.

There was a race condition in the reset path where the RX buffer could become corrupted during Fdir configuration.This is due to a HW bug.The fix right now is to lock the buffer while we do the fdir configuration.Since we were using similar workaround for another bug, I moved the existing code to a function and reused it.HW team also recommended that IXGBE_MAX_SECRX_POLL value be changed from 30 to 40.The erratum for this bug will be published in the next release 82599 Spec Update Signed-off-by: Atita Shirwaikar <atita.shirwaikar@intel.com> Acked-by: Peter P Waskiewicz Jr <peter.p.waskiewicz.jr@intel.com> Tested-by: Stephen Ko <stephen.s.ko@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

2012-03-14ixgbe: Do not disable read relaxed ordering when DCA is enabledAlexander Duyck
A previous fix had gone though and disabled relaxed ordering for Rx descriptor read fetching. This was not necessary as this functions correctly and has no ill effects on the system. In addition several of the defines used for the DCA control registers were incorrect in that they indicated descriptor effects when they actually had an impact on either data or header write back.

2012-03-13mac80211: rename bss_conf timestamp to last_tsfJohannes Berg
This value is not really very useful by itself, yet some drivers (including iwlwifi until I can figure out what it should do) use it. At least rename it to "last_tsf" to indicate the meaning and add a note that it may be really old. I suspect the value may become useful combined with the rx_status->mactime, but we don't (yet) store that value and pass it to the driver.

Recent changes in udev are causing problems for drivers that load firmware from the probe routine. As b43 has such a structure, it must be changed. As this driver loads more than 1 firmware file, changing to the asynchronous routine request_firmware_nowait() would be complicated.

2012-03-12ixgbe: Simplify logic for ethtool loopback frame creation and testingAlexander Duyck
This change makes it a bit easier to do the loopback frame creating and testing. Previously we were doing an and to drop the last bit, and then dividing the frame_size by 2 in order to get locations for frame bytes and testing. Instead we can simplify it by just shifting the register one bit to the right and using that for the frame offsets. This change also replaces all instances of rx_buffer_info with just rx_buffer since that is closer to the name of the actual structure being used and can save a few extra characters. In addition I have updated the logic for cleaning up a test frame so that we pass an rx_buffer instead of the sk_buff. The main motivation behind this is changes that will replace the sk_buff with just a page in the future.

2012-03-12ixgbe: Allocate rings as part of the q_vectorAlexander Duyck
This patch makes the rings a part of the q_vector directly instead of indirectly. Specifically on x86 systems this helps to avoid any cache set conflicts between the q_vector, the tx_rings, and the rx_rings as the critical stride is 4K and in order to cross that boundary you would need to have over 15 rings on a single q_vector. In addition this allows for smarter allocations when Flow Director is enabled. Previously Flow Director would set the irq_affinity hints based on the CPU and was still using a node interleaving approach which on some systems would end up with the two values mismatched. With the new approach we can set the affinity for the irq_vector and use the CPU for that affinity to determine the node value for the node and the rings.

2012-03-12ixgbe: Address issues with Tx WHTRESH value not being set correctlyAlexander Duyck
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 Duyck
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 Duyck
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.
