There's an info_size value stored on inet_diag_handler, but for existing code this value is effectively constant, so just use sizeof(struct tcp_info) where required. Signed-off-by:

Now RED uses a Q0.32 number to store max_p (max probability), allow RED/GRED/CHOKE to use/report full resolution at config/dump time. Old tc binaries are non aware of new attributes, and still set/get Plog. New tc binary set/get both Plog and max_p for backward compatibility, they display "probability value" if they get max_p from new kernels. # tc -d qdisc show dev ... ... qdisc red 10: parent 1:1 limit 360Kb min 30Kb max 90Kb ecn ewma 5 probability 0.09 Scell_log 15 Make sure we avoid potential divides by 0 in reciprocal_value(), if (max_th - min_th) is big.

This reverts commit 865d9f9f. This commit breaks the build with CONFIG_NETPRIO_CGROUP=y so revert it. It does build as a module though. The SUBSYS macro in the cgroup core code automatically defines a subsys structure as extern. Long term we should fix the macro. And I need to fully build test things. Tested with CONFIG_NETPRIO_CGROUP={y|m|n} with and without CONFIG_CGROUPS defined. Signed-off-by:

The code is missing initialization of NO_FCOE_FLAG and NO_ISCSI*FLAGS when CONFIG_CNIC is not selected. This causes panic during driver load since commit 1d187b34 where NO_FCOE tested unconditionally (outside #ifdef BCM_CNIC structure) and accessed fp[FCOE_IDX] which is not allocated. Reported-by:

Adaptative RED AQM for linux, based on paper from Sally FLoyd, Ramakrishna Gummadi, and Scott Shenker, August 2001 : http://icir.org/floyd/papers/adaptiveRed.pdf Goal of Adaptative RED is to make max_p a dynamic value between 1% and 50% to reach the target average queue : (max_th - min_th) / 2 Every 500 ms: if (avg > target and max_p <= 0.5) increase max_p : max_p += alpha; else if (avg < target and max_p >= 0.01) decrease max_p : max_p *= beta; target :[min_th + 0.4*(min_th - max_th), min_th + 0.6*(min_th - max_th)]. alpha : min(0.01, max_p / 4) beta : 0.9 max_P is a Q0.32 fixed point number (unsigned, with 32 bits mantissa) Changes against our RED implementation are : max_p is no longer a negative power of two (1/(2^Plog)), but a Q0.32 fixed point number, to allow full range described in Adatative paper. To deliver a random number, we now use a reciprocal divide (thats really a multiply), but this operation is done once per marked/droped packet when in RED_BETWEEN_TRESH window, so added cost (compared to previous AND operation) is near zero. dump operation gives current max_p value in a new TCA_RED_MAX_P attribute. Example on a 10Mbit link : tc qdisc add dev $DEV parent 1:1 handle 10: est 1sec 8sec red \ limit 400000 min 30000 max 90000 avpkt 1000 \ burst 55 ecn adaptative bandwidth 10Mbit # tc -s -d qdisc show dev eth3 ... qdisc red 10: parent 1:1 limit 400000b min 30000b max 90000b ecn adaptative ewma 5 max_p=0.113335 Scell_log 15 Sent 50414282 bytes 34504 pkt (dropped 35, overlimits 1392 requeues 0) rate 9749Kbit 831pps backlog 72056b 16p requeues 0 marked 1357 early 35 pdrop 0 other 0 Signed-off-by:

The .remove code is broken in several ways. - mdiobus_unregister() is called twice for the same object in case of dual FEC - phy_disconnect() is being called when the PHY is already disconnected - the requested IRQ(s) are not freed - fec_stop() is being called with the inteface already stopped All of those lead to kernel crashes if the remove function is actually used.

When the MAC address is supplied via platform_data it should be OK as it is and should not be modified in case of a dual FEC setup. Also copying the MAC from platform_data to the single 'macaddr' variable will overwrite the MAC for the first interface in case of a dual FEC setup. Signed-off-by:

If user has configured a MAC address that is not one of the existing ports of the bridge, then we need to add a special entry in the forwarding table. This forwarding table entry has no outgoing port so it has to be treated a little differently. The special entry is reported by the netlink interface with ifindex of bridge, but ignored by the old interface since there is no usable way to put it in the ABI. Reported-by:
