From cb9eff097831007afb30d64373f29d99825d0068 Mon Sep 17 00:00:00 2001 From: Patrick Ohly Date: Thu, 12 Feb 2009 05:03:36 +0000 Subject: net: new user space API for time stamping of incoming and outgoing packets User space can request hardware and/or software time stamping. Reporting of the result(s) via a new control message is enabled separately for each field in the message because some of the fields may require additional computation and thus cause overhead. User space can tell the different kinds of time stamps apart and choose what suits its needs. When a TX timestamp operation is requested, the TX skb will be cloned and the clone will be time stamped (in hardware or software) and added to the socket error queue of the skb, if the skb has a socket associated with it. The actual TX timestamp will reach userspace as a RX timestamp on the cloned packet. If timestamping is requested and no timestamping is done in the device driver (potentially this may use hardware timestamping), it will be done in software after the device's start_hard_xmit routine.

This patch adds support for multiple switch chips on a network interface. An example topology for a 16-port device with an embedded CPU is as follows: +-----+ +--------+ +--------+ | |eth0 10| switch |9 10| switch | | CPU +----------+ +-------+ | | | | chip 0 | | chip 1 | +-----+ +---++---+ +---++---+ || || || || ||1000baseT ||1000baseT ||ports 1-8 ||ports 9-16 This requires a couple of interdependent changes in the DSA layer: - The dsa platform driver data needs to be extended: there is still only one netdevice per DSA driver instance (eth0 in the example above), but each of the switch chips in the tree needs its own mii_bus device pointer, MII management bus address, and port name array. (include/net/dsa.h) The existing in-tree dsa users need some small changes to deal with this. (arch/arm) - The DSA and Ethertype DSA tagging modules need to be extended to use the DSA device ID field on receive and demultiplex the packet accordingly, and fill in the DSA device ID field on transmit according to which switch chip the packet is heading to. (net/dsa/tag_{dsa,edsa}.c) - The concept of "CPU port", which is the switch chip port that the CPU is connected to (port 10 on switch chip 0 in the example), needs to be extended with the concept of "upstream port", which is the port on the switch chip that will bring us one hop closer to the CPU (port 10 for both switch chips in the example above). - The dsa platform data needs to specify which ports on which switch chips are links to other switch chips, so that we can enable DSA tagging mode on them. (For inter-switch links, we always use non-EtherType DSA tagging, since it has lower overhead. The CPU link uses dsa or edsa tagging depending on what the 'root' switch chip supports.) This is done by specifying "dsa" for the given port in the port array. - The dsa platform data needs to be extended with information on via which port to reach any given switch chip from any given switch chip. This info is specified via the per-switch chip data struct ->rtable[] array, which gives the nexthop ports for each of the other switches in the tree. For the example topology above, the dsa platform data would look something like this: static struct dsa_chip_data sw[2] = { { .mii_bus = &foo, .sw_addr = 1, .port_names[0] = "p1", .port_names[1] = "p2", .port_names[2] = "p3", .port_names[3] = "p4", .port_names[4] = "p5", .port_names[5] = "p6", .port_names[6] = "p7", .port_names[7] = "p8", .port_names[9] = "dsa", .port_names[10] = "cpu", .rtable = (s8 []){ -1, 9, }, }, { .mii_bus = &foo, .sw_addr = 2, .port_names[0] = "p9", .port_names[1] = "p10", .port_names[2] = "p11", .port_names[3] = "p12", .port_names[4] = "p13", .port_names[5] = "p14", .port_names[6] = "p15", .port_names[7] = "p16", .port_names[10] = "dsa", .rtable = (s8 []){ 10, -1, }, }, }, static struct dsa_platform_data pd = { .netdev = &foo, .nr_switches = 2, .sw = sw, }; Signed-off-by: Lennert Buytenhek Tested-by: Gary Thomas Signed-off-by: David S.
