Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-08-27 This series contains updates to i40e and i40evf. Carolyn provides two patches, first changes the wording of the flow director add/remove and asynchronous failure messages to include the fd_id to try and add some way to track the operations on a given fd_id. Second adds a check during handle_link_event for unqualified modules when link is down and there is a module plugged in. Anjali provides four patches to i40e/i40evf. First update flow director messages so that a user can tell if a filter was added or deleted. Then updates the ATR policy to not auto-disable ATR when we have errors in programming. The disabling of ATR when we got programming errors was buggy and was still adding new rules and causing continuous errors. With this policy change, we flush instead when we see too many errors. In addition she adds a flow director flush counter to ethtool to help know how many times the interface had to flush and replay the flow director filter table. Updates the driver to ignores a driver perceived transmit hang if the number of descriptors pending is less than 4, and instead log a stat when this situation happens. This is because the queue progresses forward and the stack never experiences a real hang in these situations. Shannon provides three patches for i40e/i40evf, first enables the l2tsel bit on receive queue contexts that are assigned to VFs so that the VF can get the stripped VLAN tag. Then adds a max buffer size parameter to the print helper to be sure the code knows when to stop. Lastly, remove the complaint when removing the default MAC VLAN filter. This was because old firmware had an incorrect MAC VLAN filter that needed to be replaced at startup, and now newer firmware does not have this problem. So now we only add the new filter if the removal succeeded and no need to complain if the removal fails. Ashish provides a change to vsi->num_queue_pairs to equal the number that is configured by the VF. This limits the number of queues that are enabled/disabled and fixes the mismatch case for when a VF configures fewer queues than is allocated to it by the PF. ==================== Signed-off-by: -

Florian Fainelli says: ==================== Broadcom BCM7xxx PHY updates for new entries Another week, another set of updates for the Broadcom BCM7xxx PHY driver. This patch set cleanups the existing definitions, adds a macro to ease the addition of future chips, and finally add two new SoCs to the list of supported chips. Resending since the first patch did not make it to the list, sorry about that.

Florian Fainelli says: ==================== dsa: Broadcom Starfighter 2 switch support This patch series adds support for the Broadcom Starfighter 2 (Roboswitch successor) using the existing DSA infrastructure. This integrated switch is heavily used in Set Top Box, Cable gateways and DSL gateways products from Broadcom, and to a larger extent the new ARM-based Wi-Fi routers although slightly differently. Changes in v5 are the introduction of ETH_P_XDSA as suggested by Alexander to help capture applications see this is a multiplexed DSA approach now. Changes in v4 are the introducing of an indirection level for DSA switch tag protocols receive and transmit functions. I intentionnaly did not address one comment from Alexander who suggested to move port_names and port_dn in a separate structure since that involves touching arch/arm/ and arch/blackfin/ code which I am not yet comfortable doing. Notable changes in v3 is the preliminary patch that reworks the skb->protocol override helpers for non-Ethertype switch tags, based on feedback from Alexander Duyck. The biggest changes from v1 of this patch series are: - use the new fixed PHY helpers - improved the switch driver with more complete features (interrupts, (RG)MII configuration, memory arrays power down/up, port disabling/enable VLAN separation Future work will focus on bringing the upstream driver in feature parity with the current downstream driver, including: - adding Wake-on-LAN support to the switch - adding suspend/resume callbacks for S2/S3 Power Management modes - extending the switch register interface to cover BCM5310X SoCs ==================== Signed-off-by: -

Add support for the Broadcom Starfigther 2 switch chip using a DSA driver. This switch driver supports the following features: - configuration of the external switch port interface: MII, RevMII, RGMII and RGMII_NO_ID are supported - support for the per-port MIB counters - support for link interrupts for special ports (e.g: MoCA) - powering up/down of switch memories to conserve power when ports are unused Finally, update the compatible property for the DSA core code to match our switch top-level compatible node.

Add support for the 4-bytes Broadcom tag that built-in switches such as the Starfighter 2 might insert when receiving packets, or that we need to insert while targetting specific switch ports. We use a fake local EtherType value for this 4-bytes switch tag: ETH_P_BRCMTAG to make sure we can assign DSA-specific network operations within the DSA drivers. Signed-off-by:

In case switch port tagging is disabled (voluntarily, or the switch just does not support it), allow us to continue using the defined set of dsa_device_ops in net/dsa/slave.c. We introduce dsa_protocol_is_tagged() to check whether we need to override skb->protocol and go through the DSA-specifif packet_type function, or if we just go on and receive the SKB through the normal path.

Modify the DSA slave interface to be bound to an arbitray PHY, not just the ones that are available as child PHY devices of the switch MDIO bus. This allows us for instance to have external PHYs connected to a separate MDIO bus, but yet also connected to a given switch port. Under certain configurations, the physical port mask might not be a 1:1 mapping to the MII PHYs mask. This is the case, if e.g: Port 1 of the switch is used and connects to a PHY at a MDIO address different than 1. Introduce a phys_mii_mask variable which allows driver to implement and divert their own MDIO read/writes operations for a subset of the MDIO PHY addresses. Signed-off-by:

DSA is currently registering one packet_type function per EtherType it needs to intercept in the receive path of a DSA-enabled Ethernet device. Right now we have three of them: trailer, DSA and eDSA, and there might be more in the future, this will not scale to the addition of new protocols. This patch proceeds with adding a new layer of abstraction and two new functions: dsa_switch_rcv() which will dispatch into the tag-protocol specific receive function implemented by net/dsa/tag_*.c dsa_slave_xmit() which will dispatch into the tag-protocol specific transmit function implemented by net/dsa/tag_*.c When we do create the per-port slave network devices, we iterate over the switch protocol to assign the DSA-specific receive and transmit operations. A new fake ethertype value is used: ETH_P_XDSA to illustrate the fact that this is no longer going to look like ETH_P_DSA or ETH_P_TRAILER like it used to be. This allows us to greatly simplify the check in eth_type_trans() and always override the skb->protocol with ETH_P_XDSA for Ethernet switches tagged protocol, while also reducing the number repetitive slave netdevice_ops assignments.

Unfortunately, the USB gadget layer has this weird things where NULL skbs are passed into ops->ndo_start_xmit() in order to trigger the dev->wrap() calls to build packets. This is completely outside of the allowable range of sane arguments for the ndo_start_xmit method. All invocations of ndo_start_xmit() should be with non-NULL SKB arguments. Put back the direct call, but with a comment explaining how this is not acceptable in the long term. Reported-by:

Some platforms have special bank registers which might be used to select the correct clock or the right mode for Media Indepent Interface controllers. Sometimes, it is also required to activate vcc regulators in the right order to supply the ethernet controller at the right time. This patch is an architecture refactoring of the arc-emac device driver. It adds a new software design which allows to add specific platform glue layer. Each platform has now its own module which performs custom initialization and remove for the target and then calls to the core driver. Signed-off-by:

We are seeing situations where the driver sees a hang with less than 4 desc pending, if the driver chooses to ignore it the queue progresses forward and the stack never experiences a real hang. With this patch we will log a stat when this situation happens "tx_sluggish" will increment and we can see some more details at a higher debug level. Other than that we will ignore this particular case of Tx hang. Change-ID: I7d1d1666d990e2b12f4f6bed0d17d22e1b6410d5 Signed-off-by:
