2013-01-21dsa: use an unique and non conflicting bus name for the slave MII busFlorian Fainelli1-2/+2
The slave MII bus registered by the DSA code is using the parent MII bus as part of its name (ds->master_mii_bus_id), in case the parent MII bus name is already 16 characters long (such as d0072004.mdio-mi) we will get the following WARN_ON in dsa_switch_setup() when calling mdiobus_register(): [ 79.088782] ------------[ cut here ]------------ [ 79.093448] WARNING: at fs/sysfs/dir.c:536 sysfs_add_one+0x80/0xa0() [ 79.099831] sysfs: cannot create duplicate filename '/class/mdio_bus/d0072004.mdio-mi' This is a genuine warning, because the DSA slave MII bus will also be named d0072004.mdio-mi, and since MII_BUS_ID_SIZE is 17 characters long (with null-terminator) the following will truncate the slave MII bus id: snprintf(ds->slave_mii_bus->id, MII_BUS_ID_SIZE, "%s-%d:%.2x", ds->master_mii_bus->id, ds->pd->sw_addr); Fix this by using dsa-<switch index->:<sw_add> which is guaranteed to be unique.

2013-01-21virtio-net: introduce a new control to set macaddrAmos Kong2-4/+25
Currently we write MAC address to pci config space byte by byte, this means that we have an intermediate step where mac is wrong.

2013-01-21net: split eth_mac_addr for better error handlingStefan Hajnoczi2-6/+37

2013-01-21mcast: add multicast proxy support (IPv4 and IPv6)Nicolas Dichtel4-28/+225
This patch add the support of proxy multicast, ie being able to build a static multicast tree. It adds the support of (*,*) and (*,G) entries. The user should define an (*,*) entry which is not used for real forwarding. This entry defines the upstream in iif and contains all interfaces from the static tree in its oifs. It will be used to forward packet upstream when they come from an interface belonging to the static tree. Hence, the user should define (*,G) entries to build its static tree. Note that upstream interface must be part of oifs: packets are sent to all oifs interfaces except the input interface. This ensures to always join the whole static tree, even if the packet is not coming from the upstream interface.

2013-01-21Documentation: remove obsolete networking/multicast.txt filePaul Gortmaker2-65/+0
The original intent of this file was to list limitations in drivers/hardware relating to multicast use, back when some modest hardware from the early 1990s did not support things we might take for granted today. I was intending to delete some now-gone MCA/token ring entries in this file, but once I opened it, I found it only contained information on the earliest (pre-2000) linux networking drivers. Checking the git history shows that the file hasn't been touched since 2005. Clearly nobody is actively consulting this file as a meaningful reference. Rather than add a "YES YES YES" line for all of the drivers we currently have, lets just take advantage of the fact that nobody is using the file to delete it. This has the side benefit of not having to do a line-by-line deletion of the file content as each older driver is expired.

2013-01-21qeth: Fix HiperSockets performance regressionStefan Raspl1-1/+1
Commit 46d3ceab "tcp: TCP Small Queues" has severly degraded performance for single connection RR workloads on HiperSockets with MTU >=16K due to a conflict of the TCP Small Queues approach with our buffer scan threshold which releases buffers not frequently enough yet.

2013-01-21qeth: Support VEPA modeStefan Raspl7-67/+112
The existing port isolation mode 'forward' will now verify that the adjacent switch port supports the required reflective relay (RR) mode. This patch adds the required error handling for the cases where enabling port isolation mode 'forward' can now fail. Furthermore, once established, we never fall back from one of the port isolation modes to a non-isolated mode without further user-interaction. This includes cases where the isolation mode was enabled successfully, but ceases to work e.g. due to configuration changes at the switch port. Finally, configuring an isolation mode with the device being offline will make onlining the device fail permanently upon errors encountered until either errors are resolved or the isolation mode is changed by the user to a different mode.
