This patch makes the RX/TX byte counters for IPIP, GRE and SIT more consistent. Previously we included the external IP headers on the way out but not when the packet is inbound. The new scheme is to count payload only in both directions. For IPIP and SIT this simply means the exclusion of the external IP header. For GRE this means that we exclude the GRE header as well.

This patch adds support for Ethernet over GRE encapsulation. This is exposed to user-space with a new link type of "gretap" instead of "gre". It will create an ARPHRD_ETHER device in lieu of the usual ARPHRD_IPGRE. Note that to preserver backwards compatibility all Transparent Ethernet Bridging packets are passed to an ARPHRD_IPGRE tunnel if its key matches and there is no ARPHRD_ETHER device whose key matches more closely.

This patch adds a netlink interface that will eventually displace the existing ioctl interface. It utilises the elegant rtnl_link_ops mechanism. This also means that user-space no longer needs to rely on the tunnel interface being of type GRE to identify GRE tunnels. The identification can now occur using rtnl_link_ops. Signed-off-by:

This patch moves the dev->mtu setting out of ipgre_tunnel_bind_dev. This is in prepartion of using rtnl_link where we'll need to make the MTU setting conditional on whether the user has supplied an MTU. This also requires the move of the ipgre_tunnel_bind_dev call out of the dev->init function so that we can access the user parameters later. This patch also adds a check to prevent setting the MTU below the minimum of 68. Signed-off-by:

Now that we have dev->needed_headroom, we can use it instead of having a bogus dev->hard_header_len. This also allows us to include dev->hard_header_len in the MTU computation so that when we do have a meaningful hard_harder_len in future it is included automatically in figuring out the MTU. Incidentally, this fixes a bug where we ignored the needed_headroom field of the underlying device in calculating our own hard_header_len. Signed-off-by:

1. arch/powerpc/platforms/pasemi/gpio_mdio.c also needs to be converted over to mdiobus_{alloc,free}(). 2. drivers/net/phy/fixed.c used to embed a struct mii_bus into its struct fixed_mdio_bus and then use container_of() to go from the former to the latter. Since mii bus structures are no longer embedded, we need to do something like use the mii bus private pointer to go from mii_bus to fixed_mdio_bus instead.

This adds support for the Trailer switch tagging format. This is another tagging that doesn't explicitly mark tagged packets with a distinct ethertype, so that we need to add a similar hack in the receive path as for the Original DSA tagging format. Signed-off-by:

Add support for the Marvell 88E6131 switch chip. This chip only supports the original (ethertype-less) DSA tagging format. On the 88E6131, there is a PHY Polling Unit (PPU) which has exclusive access to each of the PHYs's MII management registers. If we want to talk to the PHYs from software, we have to disable the PPU and wait for it to complete its current transaction before we can do so, and we need to re-enable the PPU afterwards to make sure that the switch will notice changes in link state and speed on the individual ports as they occur. Since disabling the PPU is rather slow, and since MII management accesses are typically done in bursts, this patch keeps the PPU disabled for 10ms after a software access completes. This makes handling the PPU slightly more complex, but speeds up something like running ethtool on one of the switch slave interfaces from ~300ms to ~30ms on typical hardware. Signed-off-by:

Most of the DSA switches currently in the field do not support the Ethertype DSA tagging format that one of the previous patches added support for, but only the original DSA tagging format. The original DSA tagging format carries the same information as the Ethertype DSA tagging format, but with the difference that it does not have an ethertype field. In other words, when receiving a packet that is tagged with an original DSA tag, there is no way of telling in eth_type_trans() that this packet is in fact a DSA-tagged packet. This patch adds a hook into eth_type_trans() which is only compiled in if support for a switch chip that doesn't support Ethertype DSA is selected, and which checks whether there is a DSA switch driver instance attached to this network device which uses the old tag format. If so, it sets the protocol field to ETH_P_DSA without looking at the packet, so that the packet ends up in the right place. Signed-off-by:

Distributed Switch Architecture is a protocol for managing hardware switch chips. It consists of a set of MII management registers and commands to configure the switch, and an ethernet header format to signal which of the ports of the switch a packet was received from or is intended to be sent to. The switches that this driver supports are typically embedded in access points and routers, and a typical setup with a DSA switch looks something like this: +-----------+ +-----------+ | | RGMII | | | +-------+ +------ 1000baseT MDI ("WAN") | | | 6-port +------ 1000baseT MDI ("LAN1") | CPU | | ethernet +------ 1000baseT MDI ("LAN2") | |MIImgmt| switch +------ 1000baseT MDI ("LAN3") | +-------+ w/5 PHYs +------ 1000baseT MDI ("LAN4") | | | | +-----------+ +-----------+ The switch driver presents each port on the switch as a separate network interface to Linux, polls the switch to maintain software link state of those ports, forwards MII management interface accesses to those network interfaces (e.g. as done by ethtool) to the switch, and exposes the switch's hardware statistics counters via the appropriate Linux kernel interfaces. This initial patch supports the MII management interface register layout of the Marvell 88E6123, 88E6161 and 88E6165 switch chips, and supports the "Ethertype DSA" packet tagging format. (There is no officially registered ethertype for the Ethertype DSA packet format, so we just grab a random one. The ethertype to use is programmed into the switch, and the switch driver uses the value of ETH_P_EDSA for this, so this define can be changed at any time in the future if the one we chose is allocated to another protocol or if Ethertype DSA gets its own officially registered ethertype, and everything will continue to work.)

The device's carrier status is controlled via the functions netif_carrier_on() and netif_carrier_off(). These set or clear a bit indicating the carrier (aka lower level link) is down, and if the state changed, they fire off a routing netlink event. Add a call to netif_carrier_off() before register_netdev() so that the newly created device will be set to carrier down. Then when the carrier comes up for the first time, a netlink event will be generated, as the carrier changed from down to up. Otherwise the initial carrier up will appear to be changing the status from up to up, and so no event is generated since that's not a change. Signed-off-by:

It was pointed out by Breno Leitao <leitao@linux.vnet.ibm.com> that ixgb would crash on PPC when an IOMMU was in use, if change_mtu was called. It appears to be a pretty simple issue in the driver that wasn't discovered because most systems don't run with an IOMMU. The driver needs to only unmap buffers that are mapped (duh).
