Clean up watchdog reset code: - move code that checks for stuck slice to a common routine - unless there is a confirmed h/w fault, verify that a stuck slice is still stuck in the watchdog worker; if the slice is no longer stuck, abort the reset. - this removes an egregious 2000ms pause in the watchdog worker that was a diagnostic aid (to look for spurious resets) the snuck into production code. v3 includes corrections from Joe Perches Signed-off-by:

A SRAM parity error can cause a surprise link down. Since We can recover from SRAM parity errors, mask PCI surprise down events. Signed-off-by:

Ensure that our tx queues remain stopped when we stop them in myri10ge_close(). Not doing so can potentially lead to traffic being transmitted when the interface is removed, which can lead to NULL pointer dereferences. Signed-off-by:

This patch enables the 6131 family of chips to forward DSA packets to other switch chips. This is needed if multiple DSA chips are used in a device. Without this patch the chip will drop any DSA packets not destined for it. This patch only enables the forwarding of DSA packets if multiple chips are used in the switch configuration. Signed-off-by:

When receiving packets from another guest on the same hypervisor, it's generally possible to receive large packets because no segmentation is necessary and these packets are handled by LRO. However, when doing routing or bridging we must disable LRO and lose this benefit. In these cases GRO can still be used and it is very effective because the packets which are segmented in the hypervisor are received very close together and can easily be merged.

If we look closely, the 4 writes to TRANSMIT_CHL.id1 can be collapsed down into much simpler code. So do just that. This also fixes a build failure due to the I/O macros no longer getting pulled in. Their minor (and accidental) usage here gets dropped as part of the unification. Signed-off-by:

Results on dummy device can be seen in my netconf 2011 slides. These results are for a 10Gige IXGBE intel nic - on another i5 machine, very similar specs to the one used in the netconf2011 results. It turns out - this is a hell lot worse than dummy and so this patch is even more beneficial for 10G. Test setup: ---------- System under test sending packets out. Additional box connected directly dropping packets. Installed prio qdisc on the eth device and default netdev default length of 1000 used as is. The 3 prio bands each were set to 100 (didnt factor in the results). 5 packet runs were made and the middle 3 picked. results ------- The "cpu" column indicates the which cpu the sample was taken on, The "Pkt runx" carries the number of packets a cpu dequeued when forced to be in the "dequeuer" role. The "avg" for each run is the number of times each cpu should be a "dequeuer" if the system was fair. 3.0-rc4 (plain) cpu Pkt run1 Pkt run2 Pkt run3 ================================================ cpu0 21853354 21598183 22199900 cpu1 431058 473476 393159 cpu2 481975 477529 458466 cpu3 23261406 23412299 22894315 avg 11506948 11490372 11486460 3.0-rc4 with patch and default weight 64 cpu Pkt run1 Pkt run2 Pkt run3 ================================================ cpu0 13205312 13109359 13132333 cpu1 10189914 10159127 10122270 cpu2 10213871 10124367 10168722 cpu3 13165760 13164767 13096705 avg 11693714 11639405 11630008 As you can see the system is still not perfect but is a lot better than what it was before... At the moment we use the old backlog weight, weight_p which is 64 packets. It seems to be reasonably fine with that value. The system could be made more fair if we reduce the weight_p (as per my presentation), but we are going to affect the shared backlog weight. Unless deemed necessary, I think the default value is fine. If not we could add yet another knob. Signed-off-by:

Problem initially reproted and fixed by Eric Dumazet <eric.dumazet@gmail.com> netdev_stats_update() resets netdev->stats and then accumulates stats from various rings. This is wrong as stats readers can sometimes catch zero values. Use temporary variables instead for accumulating per-ring values. Signed-off-by:

Commit, commit c8ca76eb Author: John Fastabend <john.r.fastabend@intel.com> Date: Sat Mar 12 03:50:53 2011 +0000 ixgbe: DCB, further cleanups to app configuration Removed the getapp() routines from ixgbe because they are no longer needed. It also allowed the set hardware routines to use both IEEE 802.1Qaz app types and CEE app types. This added code to do bit shifting in the IEEE case. This patch reverts the checks and handles the IEEE case from the setapp entry point. I prefer this because it keeps the two paths from having to be aware of the DCB mode. This resolves a bug where I missed setting the selector bit in the IEEE spec value and left it in the CEE value. Now that they are separate routines these types of errors should not occur.
