Capacity math on ring full is wrong: we are looking at num_sg but that might be optimistic because of indirect buffer use. The implementation also penalizes fast path with extra memory accesses for the benefit of ring full condition handling which is slow path. It's easy to query ring capacity so let's do just that. This change also makes it easier to move vnet header for tx around as follow-up patch does. Signed-off-by: NMichael S.

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.

由 Hiroaki SHIMODA 提交于
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 3f0cfa3b 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 da158646. 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.

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.

由 Eric Dumazet 提交于
Current GRO can hold packets in gro_list for almost unlimited time, in case napi->poll() handler consumes its budget over and over. 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.
