In SR-IOV mode the PF driver acts as the uplink port and is used to send control packets e.g. lldpad, stp, etc. eth0.1 eth0.2 eth0 VF VF PF | | | <-- stand-in for uplink | | | -------------------------- | Embedded Switch | -------------------------- | MAC <-- uplink But the embedded switch is setup to forward multicast addresses to all interfaces both VFs and PF and onto the physical link. This results in reserved MAC addresses used by control protocols to be forwarded over the switch onto the VF. In the LLDP case the PF sends an LLDPDU and it is currently being forwarded to all the VFs who then see the PF as a peer. This is incorrect. This patch adds the multicast addresses to the RAR table in the hardware to prevent this behavior. Signed-off-by:John Fastabend <john.r.fastabend@intel.com> Tested-by:

The function to set the macvlan filter should return success or failure instead of the index of the filter. The message processing function was misinterpreting the index as a non-zero return code indicating failure and NACKing MAC filter set messages that actually succeeded. Signed-off-by:

Calling the ixgbe_reset_pipeline_82599 function will ensure a full pipeline reset on all 82599 devices. This is necessary to avoid possible link issues. Since this patch accomplishes this by modifying AUTOC.LMS we need to wrap all AUTOC writes when LESM is enabled. v2- fix LMS behaviour based on feedback by Martin Josefsson CC: Martin Josefsson <gandalf@mjufs.se> Signed-off-by:

Pablo Neira Ayuso says: ==================== The following changeset contains updates for IPVS from Jesper Dangaard Brouer that did not reach the previous merge window in time. More specifically, updates to improve IPv6 support in IPVS. More relevantly, some of the existing code performed wrong handling of the extensions headers and better fragmentation handling. Jesper promised more follow-up patches to refine this after this batch hits net-next. Yet to come. ==================== Signed-off-by: -

The cgroup logic part of net_cls is very similar as the one in net_prio. Let's stream line the net_cls logic with the net_prio one. The net_prio update logic was changed by following commit (note there were some changes necessary later on) commit 406a3c63 Author: John Fastabend <john.r.fastabend@intel.com> Date: Fri Jul 20 10:39:25 2012 +0000 net: netprio_cgroup: rework update socket logic Instead of updating the sk_cgrp_prioidx struct field on every send this only updates the field when a task is moved via cgroup infrastructure. This allows sockets that may be used by a kernel worker thread to be managed. For example in the iscsi case today a user can put iscsid in a netprio cgroup and control traffic will be sent with the correct sk_cgrp_prioidx value set but as soon as data is sent the kernel worker thread isssues a send and sk_cgrp_prioidx is updated with the kernel worker threads value which is the default case. It seems more correct to only update the field when the user explicitly sets it via control group infrastructure. This allows the users to manage sockets that may be used with other threads. Since classid is now updated when the task is moved between the cgroups, we don't have to call sock_update_classid() from various places to ensure we always using the latest classid value. [v2: Use iterate_fd() instead of open coding] Signed-off-by:

sock_update_classid() assumes that the update operation always are applied on the current task. sock_update_classid() needs to know on which tasks to work on in order to be able to migrate task between cgroups using the struct cgroup_subsys attach() callback. Signed-off-by:

This patch introduces the below 3 usb command helpers: usbnet_read_cmd / usbnet_write_cmd / usbnet_write_cmd_async so that each low level driver doesn't need to implement them by itself, and the dma buffer allocation for usb transfer and runtime PM things can be handled just in one place. Acked-by:

Currently sctp allows for the optional use of md5 of sha1 hmac algorithms to generate cookie values when establishing new connections via two build time config options. Theres no real reason to make this a static selection. We can add a sysctl that allows for the dynamic selection of these algorithms at run time, with the default value determined by the corresponding crypto library availability. This comes in handy when, for example running a system in FIPS mode, where use of md5 is disallowed, but SHA1 is permitted. Note: This new sysctl has no corresponding socket option to select the cookie hmac algorithm. I chose not to implement that intentionally, as RFC 6458 contains no option for this value, and I opted not to pollute the socket option namespace. Change notes: v2) * Updated subject to have the proper sctp prefix as per Dave M. * Replaced deafult selection options with new options that allow developers to explicitly select available hmac algs at build time as per suggestion by Vlad Y.

This tiny patch removes two unused err assignments. In those two cases the err variable is either overwritten with another value at a later point in time without having read the previous assigment, or it is assigned and the function returns without using/reading err after the assignment.

Enable ALDPS function to save power when link down. Note that the feature should be set after the other PHY settings. And the firmware is necessary. Don't enable it without loading the firmware. None of the firmware-free chipsets support ALDPS. Neither do the RTL8168d/8111d. For 8136 series, make sure the ALDPS is disabled before loading the firmware. For 8168 series, the ALDPS would be disabled automatically when loading firmware. You must not disable it directly. Signed-off-by:
