2013-05-30tcp: undo on DSACK during recoveryYuchung Cheng1-1/+7
If the receiver supports DSACK, sender can detect false recoveries and revert cwnd reductions triggered by either severe network reordering or concurrent reordering and loss event.

2013-05-30tcp: fix undo on partial ack in recoveryYuchung Cheng1-26/+33
Upon detecting spurious fast retransmit via timestamps during recovery, use PRR to clock out new data packet instead of retransmission. Once all retransmission are proven spurious, the sender then reverts the cwnd reduction and congestion state to open or disorder. The current code does the opposite: it undoes cwnd as soon as any retransmission is spurious and continues to retransmit until all data are acked. This nullifies the point to undo the cwnd because the sender is still retransmistting spuriously. This patch fixes it. The undo_ssthresh argument of tcp_undo_cwnd_reductiuon() is no longer needed and is removed.

2013-05-30tcp: consolidate PRR packet accountingYuchung Cheng1-25/+20
This patch series fixes an undo bug in fast recovery: the sender mistakenly undos the cwnd too early but continues fast retransmits until all pending data are acked. This also multiplies the SNMP stat PARTIALUNDO events by the degree of the network reordering. The first patch prepares the fix by consolidating the accounting of newly_acked_sacked in tcp_cwnd_reduction(), instead of updating newly_acked_sacked everytime sacked_out is adjusted. Also pass acked and prior_unsacked as const type because they are readonly in the rest of recovery processing.

2013-05-30net: mv643xx_eth: add DT parsing supportSebastian Hesselbarth2-4/+234
This adds device tree parsing support for the shared driver of mv643xx_eth. As the bindings are slightly different from current PPC bindings new binding documentation is also added. Following PPC-style device setup, the shared driver now also adds port platform_devices and sets up port platform_data.

2013-05-30net: mv643xx_eth: proper initialization for Kirkwood SoCsSebastian Hesselbarth1-0/+11
Ethernet controllers found on Kirkwood SoCs not only suffer from loosing MAC address register contents on clock gating but also some important registers are reset to values that would break ethernet. This patch clears the CLK125_BYPASS_EN bit for DT enabled Kirkwood only by using of_device_is_compatible() instead of #ifdefs. Non-DT Kirkwood is not affected as it installs a clock gating workaround because of the MAC address issue above. Other Orion SoCs do not suffer from register reset, do not have the bit in question, or do not have the register at all. Moreover, system controllers on PPC using this driver should also be protected from clearing that bit. Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com> Signed-off-by: David S.

2013-05-28net, ipv4, ipv6: Correct assignment of skb->network_header to skb->tailSimon Horman4-4/+38
This corrects an regression introduced by "net: Use 16bits for *_headers fields of struct skbuff" when NET_SKBUFF_DATA_USES_OFFSET is not set. In that case skb->tail will be a pointer however skb->network_header is now an offset. This patch corrects the problem by adding a wrapper to return skb tail as an offset regardless of the value of NET_SKBUFF_DATA_USES_OFFSET. It seems that skb->tail that this offset may be more than 64k and some care has been taken to treat such cases as an error. Signed-off-by: Simon Horman <horms@verge.net.au> Signed-off-by: David S.
