Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to e1000e only. David provides four fixes for e1000e, first is a workaround for a hardware erratum on 82579 devices which experienced packet loss in gigabit and 100 speeds when interconnect between the PHY and MAC is exiting K1 power saving state. Second expands the scope of a workaround to include i217 and i218 parts as well to address over aggressive transmit behavior when connecting at 10Mbs half-duplex. Next is to resolve a reported link flap issue on 82579 parts which was root caused as an interoperability problem between 82579 and at least some Broadcom PHYs in the Energy Efficient Ethernet wake mechanism. Lastly, restricts the workaround of putting the PHY into MDIO slow mode to access the PHY id to relevant parts since this issue has been fixed on the newer hardware. ==================== Signed-off-by: NDavid S.

It has been determined that the workaround of putting the PHY into MDIO slow mode to access the PHY id is not necessary with Lynx Point and newer parts. The issue that necessitated the workaround has been fixed on the newer hardware. We will maintains, as a last ditch attempt, the conversion to MDIO Slow Mode in the failure branch when attempting to access the PHY id so as to cover all contingencies.

Several customers have reported a link flap issue on 82579. The symptoms are random and intermittent link losses when 82579 is connected to specific link partners. Issue has been root caused as interoperability problem between 82579 and at least some Broadcom PHYs in the Energy Efficient Ethernet wake mechanism. To fix the issue, we are disabling the Phase Locked Loop shutdown in 100M Low Power Idle. This solution will cause an increase of power in 100M EEE link. It will cost additional 28mW in this specific mode.

In commit 772d05c5 "e1000e: slow performance between two 82579 connected via 10Mbit hub", a workaround was put into place to address the overaggressive transmit behavior of 82579 parts when connecting at 10Mbs half-duplex. This same behavior is seen on i217 and i218 parts as well. This patch expands the original workaround to encompass these parts.

This is a workaround for a HW erratum on 82579 devices. Erratum is #23 in Intel 6 Series Chipset and Intel C200 Series Chipset specification Update June 2013. Problem: 82579 parts experience packet loss in Gig and 100 speeds when interconnect between PHY and MAC is exiting K1 power saving state. This was previously believed to only affect 1Gig speed, but has been observed at 100Mbs also. Workaround: Disable K1 for 82579 devices at Gig and 100 speeds.

Commit 4d619f62 ("net: cdc_ncm: no point in filling up the NTBs if we send ZLPs") changed the padding logic for devices with the ZLP flag set. This meant that frames of any size will be sent without additional padding, except for the single byte added if the size is a multiple of the USB packet size. But if the unpadded size is identical to the maximum frame size, and the maximum size is a multiplum of the USB packet size, then this one-byte padding will overflow the buffer. Prevent padding if already at maximum frame size, letting usbnet transmit a ZLP instead in this case.

For phy devices that don't issue interrupts upon link state changes, phylib polls the link state resulting in repeated calls to adjust_link(), even if the link state didn't change. As a result, some mac registers are repeatedly read and written with the same values, which is not ok. To fix this, adjust_link() has been refactored to check first whether the link state has changed and to take action only if needed, updating mac registers and local state variables. The 'new_state' local flag, set if one of the link params changed (link, speed or duplex), has been rendered useless and removed by this refactoring.

commit b9f47a3a (tcp_cubic: limit delayed_ack ratio to prevent divide error) try to prevent divide error, but there is still a little chance that delayed_ack can reach zero. In case the param cnt get negative value, then ratio+cnt would overflow and may happen to be zero. As a result, min(ratio, ACK_RATIO_LIMIT) will calculate to be zero. In some old kernels, such as 2.6.32, there is a bug that would pass negative param, which then ultimately leads to this divide error. commit 5b35e1e6 (tcp: fix tcp_trim_head() to adjust segment count with skb MSS) fixed the negative param issue. However, it's safe that we fix the range of delayed_ack as well, to make sure we do not hit a divide by zero.

This reverts commit 12a2856b. The commit above doesn't appear to be necessary any more as the checksums appear to be correctly computed/validated. Additionally the above commit breaks kvm configurations where one VM is using a device that support checksum offload (virtio) and the other VM does not. In this case, packets leaving virtio device will have CHECKSUM_PARTIAL set. The packets is forwarded to a macvtap that has offload features turned off. Since we use CHECKSUM_UNNECESSARY, the host does does not update the checksum and thus a bad checksum is passed up to the guest.

The following is a problematic configuration: VM1: virtio-net device connected to macvtap0@eth0 VM2: e1000 device connect to macvtap1@eth0 The problem is is that virtio-net supports checksum offloading and thus sends the packets to the host with CHECKSUM_PARTIAL set. On the other hand, e1000 does not support any acceleration. For small TCP packets (and this includes the 3-way handshake), e1000 ends up receiving packets that only have a partial checksum set. This causes TCP to fail checksum validation and to drop packets. As a result tcp connections can not be established. Commit 3e4f8b78 macvtap: Perform GSO on forwarding path. fixes this issue for large packets wthat will end up undergoing GSO. This commit adds a check for the non-GSO case and attempts to compute the checksum for partially checksummed packets in the non-GSO case.

Since the tx queueing rework, pausing per-tid queues on aggregation session setup is no longer necessary.

When the amount of noise fluctuates strongly, low immunity settings can sometimes disrupt signal detection on AR913x chips. When that happens, no OFDM/CCK errors are reported anymore, and ANI tunes the radio to the lowest immunity settings. Usually rx/tx fails as well in that case. To fix this, keep noise immunity settings at or above ANI default level, which will keep radio parameters at or above INI values.
