* mcs7830: Fix link state detectionOndrej Zary2012-10-121-9/+21
| | | | | | | | | | | | The device had an undocumented "feature": it can provide a sequence of spurious link-down status data even if the link is up all the time. A sequence of 10 was seen so update the link state only after the device reports the same link state 20 times.

| | | | | | | | | | | | | | | Based on patch from Matthew Garrett <mjg@redhat.com> (https://lkml.org/lkml/2011/11/11/168). http://driveragent.com/archive/30421/7-0-14 indicates that ASPM is disabled on the 250 and 260.

* e1000e: Change wthresh to 1 to avoid possible Tx stallsHiroaki SHIMODA2012-10-102-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch originated from Hiroaki SHIMODA but has been modified by Intel with some minor cleanups and additional commit log text. Denys Fedoryshchenko and others reported Tx stalls on e1000e with BQL enabled. Issue was root caused to hardware delays. They were introduced because some of the e1000e hardware with transmit writeback bursting enabled, waits until the driver does an explict flush OR there are WTHRESH descriptors to write back. Sometimes the delays in question were on the order of seconds, causing visible lag for ssh sessions and unacceptable tx completion latency, especially for BQL enabled kernels. To avoid possible Tx stalls, change WTHRESH back to 1. The current plan is to investigate a method for re-enabling WTHRESH while not harming BQL, but those patches will be later for net-next if they work. please enqueue for stable since v3.3 as this bug was introduced in commit 3f0cfa3bc11e7f00c9994e0f469cbc0e7da7b00c Author: Tom Herbert <therbert@google.com> Date: Mon Nov 28 16:33:16 2011 +0000 e1000e: Support for byte queue limits Changes to e1000e to use byte queue limits.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fengguang reported a kernel build failure as following: drivers/built-in.o: In function `pch_gbe_ioctl': pch_gbe_main.c:(.text+0x510370): undefined reference to `pch_ch_control_write' pch_gbe_main.c:(.text+0x510393): undefined reference to `pch_ch_control_write' pch_gbe_main.c:(.text+0x5103b3): undefined reference to `pch_ch_control_write' ... It's a regression by commit da1586461. The root cause is that the CONFIG_PPS is not set there, consequently CONFIG_PTP_1588_CLOCK can not be set anyway, which finally causes ptp_pch and pch_gbe_main build failures. As David prefers to use *select* to fix such module co-dependency issues, this patch explicitly selects all the possible dependencies of PCH_PTP.

| | * | | mlx4_core: Adjust flow steering attach wrapper so that IB works on SR-IOV VFsJack Morgenstein2012-10-031-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the InfiniBand stack does not support flow steering at the verbs level -- the only usage of flow steering in the IB driver is for L2 multicast attaches. We need to add the IB case to procedure mlx4_QP_FLOW_STEERING_ATTACH_wrapper() to allow IPoIB to work on VFs on ConnectX-3 when flow steering is enabled. Currently, the IB case in mlx4_QP_FLOW_STEERING_ATTACH_wrapper() is missing, so the procedure returns -EINVAL and IPoIB on VFs breaks.

* | | | | ixgbe/ixgbevf: Limit maximum jumbo frame size to 9.5K to avoid Tx hangsAlexander Duyck2012-10-092-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change limits the PF/VF driver to 9.5K max jumbo frame size in order prevent a possible Tx hang in the adapter when sending frames between pools. All of the parts in ixgbe support a maximum frame of 15.5K for standard traffic, however with SR-IOV or DCB enabled they should be limiting the MTU size to 9.5K. Instead of adding extra checks which would have to change the MTU when we go into or out of these modes it is preferred to just use a standard 9.5K MTU limit for all modes so that this extra overhead can be avoided.

This caused some serious issues such as Tx hangs and extremely poor performance with some usages of the driver. The issue is best observed by running: iperf -c <host> -P <n> Where n is greater than one. The greater the value of n the more likely the problem is to show up.

In this case, napi_complete()/napi_gro_flush() are not called. Another problem is that gro_list is flushed in non friendly way : We scan the list and complete packets in the reverse order. (youngest packets first, oldest packets last) This defeats priorities that sender could have cooked. Since GRO currently only store TCP packets, we dont really notice the bug because of retransmits, but this behavior can add unexpected latencies, particularly on mice flows clamped by elephant flows. This patch makes sure no packet can stay more than 1 ms in queue, and only in stress situations. It also complete packets in the right order to minimize latencies.
