In keeping with the e1000e driver function naming convention, the subject function is renamed to indicate it is generic, i.e. it is applicable to more than just a single MAC family (e.g. 80003es2lan, 82571, ich8lan). Signed-off-by:

Remove the function e1000_force_speed_duplex() and replace the single call to it with the same function pointer that it would call. The function pointer is always set so there is no risk of a NULL pointer dereference. Signed-off-by:

The comments here say that the /* Max event is 61 char */ but in 2003 we changed the event format and now the max event size is 75. The longest event is: "Discovered %08x (%s) behind %08x {hints %02X-%02X}\n", 12345678901 23 456789012 34567890 1 2 3 +8 +21 +8 +2 +2 +1 = 75 characters. There was a check to return -EOVERFLOW if the user gave us a "count" value that was less than 64. Raising it to 75 might break backwards compatability. Instead I removed the check and now it returns a truncated string if "count" is too low. Signed-off-by:Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by:

Jeff Kirsher says: ==================== This series contains updates to e1000e only. All the updates come from Bruce Allan and most of the patch fix or enable features on i217/i218. Most notably is patch 03 "e1000e: add support for IEEE-1588 PTP", which is v2 of the patch based on feedback from Stephen Hemminger. Also patch 04 "e1000e: enable ECC on I217/I218 to catch packet buffer memory errors" should be queued up for stable (as well as net) trees, but the patch does not apply cleanly to either of those trees currently. So I will work with Bruce to provide a version of the patch which will apply cleanly to net (and stable) and we can queue it up at that point for stable 3.5 tree. The remaining patches are general cleanups of the code. ==================== Signed-off-by:

Static analysis with cppcheck has shown a few instances of a variable being reassigned a value before the old one has been used. None of these ever require the old value to be used so remove the old values. Signed-off-by:

Static analysis with cppcheck has shown a few instances of a variable which is assigned a value that is never used. A number of these are the return status of various driver function calls which should be passed back to the caller of the current function. Signed-off-by:

Toggling the LANPHYPC Value bit cycles the power on the PHY and sets it back to power-on defaults. This includes setting it's MAC-PHY messaging mode to use the PCIe-like interconnect, so the MAC must also be set back from SMBus mode to PCIe mode otherwise the PHY can be inaccessible. Signed-off-by:

As done with the previous generation managed 82579, prevent the PHY from being put into an unknown state by blocking the hardware from automatically configuring the PHY as done with the previous generation managed 82579. Instead, the driver should configure the PHY with contents of the EEPROM image. Signed-off-by:

In rare instances, memory errors have been detected in the internal packet buffer memory on I217/I218 when stressed under certain environmental conditions. Enable Error Correcting Code (ECC) in hardware to catch both correctable and uncorrectable errors. Correctable errors will be handled by the hardware. Uncorrectable errors in the packet buffer will cause the packet to be received with an error indication in the buffer descriptor causing the packet to be discarded. If the uncorrectable error is in the descriptor itself, the hardware will stop and interrupt the driver indicating the error. The driver will then reset the hardware in order to clear the error and restart. Both types of errors will be accounted for in statistics counters. Signed-off-by:

The SHRAH[9] register on I217 has a different R/W bit-mask than RAR and SHRAL/H registers. Set R/W bit-mask appropriately for SHRAH[9] when testing the R/W ability of the register. Also, fix the error message log format so that it does not provide misleading information (i.e. the logged register address could be incorrect). Signed-off-by:

Pablo Neira Ayuso says: ==================== This batch contains netfilter updates for you net-next tree, they are: * The new connlabel extension for x_tables, that allows us to attach labels to each conntrack flow. The kernel implementation uses a bitmask and there's a file in user-space that maps the bits with the corresponding string for each existing label. By now, you can attach up to 128 overlapping labels. From Florian Westphal. * A new round of improvements for the netns support for conntrack. Gao feng has moved many of the initialization code of each module of the netns init path. He also made several code refactoring, that code looks cleaner to me now. * Added documentation for all possible tweaks for nf_conntrack via sysctl, from Jiri Pirko. * Cisco 7941/7945 IP phone support for our SIP conntrack helper, from Kevin Cernekee. * Missing header file in the snmp helper, from Stephen Hemminger. * Finally, a couple of fixes to resolve minor issues with these changes, from myself. ==================== Signed-off-by:

There is no actual dependency on initialization of the mailbox ops on whether SR-IOV is enabled or not and it doesn't hurt to go ahead and initialize ops unconditionally.

This change is meant to inline the Rx PTP descriptor handling. The main motivation is to avoid unnecessary jumps into function calls that we then immediately exit because we are not performing timestamps. The net result of this change is that ixgbe_ptp_rx_tstamp drops from .5% CPU utilization in my performance runs to 0%, and the only value tested is the Rx descriptor which should already be warm in the cache if not stored in a register.
