* | e1000e: add support for hardware timestamping on some devicesBruce Allan2013-01-18
| | | | | | | | | | | | | | | | | | | | | | | | On 82574, 82583, 82579, I217 and I218 add support for hardware time stamping of all or no Rx packets and Tx packets which have the SKBTX_HW_TSTAMP flag set. Update the .get_ts_info ethtool operation to report the supported time stamping modes, and enable and disable hardware time stamping with the SIOCSHWTSTAMP ioctl.

* | e1000e: Use standard #defines for PCIe Capability ASPM fieldsBjorn Helgaas2013-01-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use the standard #defines for PCIe Capability ASPM fields. Previously we used PCIE_LINK_STATE_L0S and PCIE_LINK_STATE_L1 directly, but these are defined for the Linux ASPM interfaces, e.g., pci_disable_link_state(), and only coincidentally match the actual register bits. PCIE_LINK_STATE_CLKPM, also part of that interface, does not match the register bit.

* | e1000e: unexpected "Reset adapter" message when cable pulledBruce Allan2013-01-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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). Re-name the FLAG_RX_RESTART_NOW to FLAG_RESTART_NOW since it is used for resets in both the Rx and Tx specific code.

* | e1000e: fix enabling of EEE on 82579 and I217Bruce Allan2013-01-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Energy Efficient Ethernet on 82579 and I217 should only be enabled if not disabled by the user, if the link is full duplex and the link partner has similar EEE capabilities (stored in different EMI registers on the two different parts). After enabling EEE, read the IEEE MMD register 3.1 (which is also stored in different EMI registers on the two different parts) to clear the count of received Tx/Rx LPI indications. Also, rename I217_EEE_100_SUPPORTED to I82579_EEE_100_SUPPORTED to indicate the bit is valid starting with I82579 (released before I217).

| | | | | | | | | | | | | | | | | | | | | | | | | | When data blocks are written to the EEPROM, the HW/SW/FW semaphore must be held for the duration. With large data blocks on 80003es2lan, 82571 and 82572, this can take too long and cause the firmware to take ownership of the semaphore and consequently ownership of writes to the EEPROM. Instead, acquire and release the semaphore for each page of the block written.

* | ixgbe: check whether thermal sensor is enabled.Jacob Keller2012-12-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | ixgbe: Fix incorrect disabling of Tx hang check in case of PFCParikh, Neerav2012-11-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The XOFF received statistic registers are per priority based and not per traffic class. The ixgbe driver was incorrectly considering them to be for each traffic class; and then disabling the "Tx hang" check for the queues that belonged to the particular traffic class that had received PFC frames. The above logic worked fine in scenario where the user priority and traffic class number matched e.g. priority 0 is mapped to traffic class 0 and so on. But, when multiple user priorities are mapped to a single traffic class or when user priorities and traffic class numbers do not line up; the ixgbe driver may disable the "Tx hang" check for queues belonging to a traffic class that did not receive PFC frames and keep the "Tx hang" check enabled for the queues that did receive the PFC frames. This patch corrects the above in the code by considering the statistics on a per priority basis; then getting the traffic class the user priority belongs to and disabling the "Tx hang" check for queues that belong to that traffic class.

* | ixgbe: Drop RLPML configuration from x540 RXDCTL register configurationAlexander Duyck2012-11-28
| | | | | | | | | | | | | | | | | | | | | | Since we are doing a page based receive there is no point in setting a maximum packet length on the x540 RXDCTL register. As such we can drop the code from the driver entirely.

* | igb: Use a 32-bit mask when calculating the flow control watermarksMatthew Vick2012-11-28
| | | | | | | | | | | | | | | | | | | | For some devices, the result of the flow control high watermark gets truncated when programming it into the registers because of the mask used. Switch the mask to 32-bit to prevent this from happening.

Check for this condition and swab the tag if needed.

* | igb: Do not parse past IP header on fragments beyond the firstAlexander Duyck2012-11-22
| | | | | | | | | | | | | | | | | | | | | | | | This change makes it so that only the first fragment in a series of fragments will have the L4 header pulled. Previously we were always pulling the L4 header as well and in the case of UDP this can harm performance since only the first fragment will have the header, the rest just contain data which should be left in the paged portion of the packet.

* | igb: No longer rely on APME to determine WoL settingsMatthew Vick2012-11-22
| | | | | | | | | | | | | | | | | | | | | | | | Historically, we've been using the APME bit to determine whether a device supports wake on a given port or not. However, this bit specifies the default wake setting, rather than the wake support. Change the behavior so that we use a flag to keep the capabilities separate from the enablement while meeting customer requirements.

* | ixgbe: fdb: only allow NUD_PERM fdb entriesJohn Fastabend2012-11-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There was a bitwise operation error in the fdb_add block that was only allowing FDB types that were not permanent. This was the opposite of the intent because the hardware never ages out address these are the _only_ type of addrs that should be allowed. This was missed because until recently iproute2 did not set any bit for this by default. And our test code to manage FDB entries on embedded devices similarly did not set these bits. I am going to chalk this up as a bug and fix it now.
