* igb: output register's information related to RX/TX queue[4-15]Koki Sanagi2012-05-10
| | | | | | | | | | | | Current igb outputs registers related to TX/RX queues(ex. RDT, RDH, TDT, TDH). But it thinks the number of RX/TX queues is 4. But 82576 has 16 RX/TX queues. This patch modifies igb to output the rest of the registers if the device is 82576.

In 'net' we added a bug fix to make iwlwifi report a more accurate skb->truesize but this conflicted with RX path changes that happened meanwhile in net-next. In e1000e a conflict arose in the validation code for settings of adapter->itr. 'net-next' had more sophisticated logic so that logic was used. Signed-off-by: David S. Miller <davem@davemloft.net>
| * igb, ixgbe: netdev_tx_reset_queue incorrectly called from tx init pathJohn Fastabend2012-05-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | igb and ixgbe incorrectly call netdev_tx_reset_queue() from i{gb|xgbe}_clean_tx_ring() this sort of works in most cases except when the number of real tx queues changes. When the number of real tx queues changes netdev_tx_reset_queue() only gets called on the new number of queues so when we reduce the number of queues we risk triggering the watchdog timer and repeated device resets. So this is not only a cosmetic issue but causes real bugs. For example enabling/disabling DCB or FCoE in ixgbe will trigger this.

* | igb: Force flow control off during reset when forcing speed.Matthew Vick2012-04-27
| | | | | | | | | | | | | | | | | | | | | | During igb_reset(), we initiate a hardware reset which will clear our flow control settings. For auto-negotiation, we re-negotiate them when linking up again, but we need to force them off properly for the forced speed case.

* | igb: add PTP Hardware Clock codeRichard Cochran2012-04-04
|/ | | | | | | | | | | | | | | | This patch adds a source file implementing a PHC. Only the basic clock operations have been implemented, although the hardware would offer some ancillary functions. The code is fairly self contained and is not yet used in the main igb driver. Every timestamp and clock read operation must consult the overflow counter to form a correct time value. Access to the counter is protected by a spin lock, and the counter is implemented using the standard cyclecounter/timecounter code.

* net: Fix issue with netdev_tx_reset_queue not resetting queue from XOFF stateAlexander Duyck2012-03-12
| | | | | | | | | | | | | | | | 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.
