2011-02-25netem: define NETEM_DIST_MAXstephen hemminger2-1/+2
Rather than magic constant in code, expose the maximum size of packet distribution table in API. In iproute2, q_netem defines MAX_DIST as 16K already. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-02-25ipv4: Rearrange how ip_route_newports() gets port keys.David S. Miller3-12/+23
ip_route_newports() is the only place in the entire kernel that cares about the port members in the routing cache entry's lookup flow key. Therefore the only reason we store an entire flow inside of the struct rtentry is for this one special case. Rewrite ip_route_newports() such that: 1) The caller passes in the original port values, so we don't need to use the rth->fl.fl_ip_{s,d}port values to remember them. 2) The lookup flow is constructed by hand instead of being copied from the routing cache entry's flow.

2011-02-24igb: add support for VF Transmit rate limit using iproute2Lior Levy4-2/+99
Implemented igb_ndo_set_vf_bw function which is being used by iproute2 tool. In addition, updated igb_ndo_get_vf_config function to show the actual rate limit to the user. The rate limitation can be configured only when the link is up. The rate limit value can be ranged between 0 and actual link speed measured in Mbps. A value of '0' disables the rate limit for this specific VF. iproute2 usage will be 'ip link set ethX vf Y rate Z'. After the command is made, the rate will be changed instantly. To view the current rate limit, use 'ip link show ethX'. The rates will be zeroed only upon driver reload or a link speed change. This feature is being supported only by 82576 device.

2011-02-24tipc: Avoid reliable broadcast preparation for NACK messagesAllan Stephens1-0/+1
Enhance TIPC to skip unnecessary (and, in some cases, redundant) preparation work when sending a broadcast link NACK message, since this preparation is only required for broadcast messages that are sent in a reliable manner. This change also fixes a bug that caused NACK messages to be improperly counted as "TX packets" in TIPC's broadcast link statistics.

2011-02-24tipc: Remove unused message header field for requested number of linksAllan Stephens5-22/+5
Eliminates support for the "number of requested links" field in a neighbor discovery message. This field was never used and has been removed from the TIPC 2.0 protocol specification. Signed-off-by: Allan Stephens <Allan.Stephens@windriver.com> Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-02-24tipc: Remove support for per-connection message sequence numberingAllan Stephens4-46/+3
Eliminates TIPC's prototype support for message sequence numbering on routable connections (i.e. connections requiring more than one hop). This capability isn't currently used, and can be removed since TIPC only supports systems in which all inter-node communication can be achieved in a single hop.

2011-02-24tipc: Add in missing lock during link initializationAllan Stephens1-0/+2
Ensure that the routine that starts up processing on a newly created link endpoint takes the spinlock of the node object that owns the link, to prevent possible conflicts with processing involving other links owned by that node object.

2011-02-24tipc: Fix port counter handling to correct congestion controlAllan Stephens2-21/+36
Modifies TIPC's congestion control between a connected port and its peer so that it works as documented. The following changes have been made: 1) The counter of the number of messages sent by a port now starts at zero, rather than one. This prevents the port from reporting port congestion one message earlier than it was supposed to. 2) The counter of the number of messages sent by a port is now incremented only if a non-empty message is sent successfully. This prevents the port from becoming permanently congested if too many send attempts are unsuccessful because of congestion (or other reasons). It also removes the risk that empty hand- shaking messages used during connection setup might cause the port to report congestion earlier than it was supposed to. 3) The counter of the number of unacknowledged messages received by a port controlled by an internal TIPC service is now incremented only if the message is non-empty, in order to be consistent with the aforementioned changes.

2011-02-24tipc: Minor optimization to topology service connection establishmentAllan Stephens1-3/+1
Eliminates a local iovec structure containing no data, which was previously used during the establishment of a topology service connection, since the same effect can be achieved by passing in a NULL pointer and an iovec length of zero.

2011-02-24tipc: Set unused probe field of link protocol messages to defined valueAllan Stephens1-0/+1
Ensures that a link reset or activate message has a "probe" field of zero. (This field is currently unused in these messages, but this could potentially change in future versions of TIPC.)

2011-02-24tipc: Improve accuracy of link transmit queue maximum size statisticAllan Stephens3-20/+9
Enhances TIPC's unicast and broadcast link code to update the transmit queue maximum size counter in a single place, namely the routine that adds messages to the queue. This ensures that the maximum size statistic reported for unicast links is completely accurate, rather than being partially based on statistical sampling. The changes to link.h are just documenting the roles of the variables. Signed-off-by: Allan Stephens <Allan.Stephens@windriver.com> Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-02-24tipc: Eliminate unnecessary locking when starting topology serviceAllan Stephens1-3/+0
Modifies the initialization code for TIPC's topology service to avoid taking the spinlock protecting the subscriber list, since there is no need to do this. Signed-off-by: Allan Stephens <Allan.Stephens@windriver.com> Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-02-24tipc: Clean up tracking of node requesting a broadcast retransmitAllan Stephens3-4/+17
Allows the broadcast link to track the node that is requesting a retransmit in a new field dedicated to that purpose. This replaces the existing mechanism that (ab)uses an existing node structure linked list field to do the tracking.

2011-02-24tipc: Clean out all remaining instances of #if 0'd unused codeAllan Stephens2-34/+2
Remove all instances of legacy or proposed-but-not-implemented code that lives within an #if 0 ... #endif block. If some of it is needed in the future it can recovered out of history, but there is no need for it to clutter up the active code base.
