Highbank and Midway xgmac h/w have different number of MAC address filter registers with 7 and 31, respectively. Highbank has been wrong, so fix it and detect the number of filter registers at run-time. Unfortunately, the version register is the same on both SOCs, so simply test if write to the last filter register will take a value. It always reads as 0 if not.

In commit 2ee68f62 (net: calxedaxgmac: fix various errors in xgmac_set_rx_mode), a fix to clean-up old address entries was added. However, the loop to zero out the entries failed to increment the register address resulting in only 1 entry getting cleared. Fix this to correctly use the loop index. Also, the end of the loop condition was off by 1 and should have been <= rather than <. Signed-off-by: NRob Herring <rob.herring@calxeda.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

FQ rate limiting suffers from two problems, reported by Steinar : 1) FQ enforces a delay when flow quantum is exhausted in order to reduce cpu overhead. But if packets are small, current delay computation is slightly wrong, and observed rates can be too high. Steinar had this problem because he disabled TSO and GSO, and default FQ quantum is 2*1514. (Of course, I wish recent TSO auto sizing changes will help to not having to disable TSO in the first place) 2) maxrate was not used for forwarded flows (skbs not attached to a socket) Tested: tc qdisc add dev eth0 root est 1sec 4sec fq maxrate 8Mbit netperf -H lpq84 -l 1000 & sleep 10 ; tc -s qdisc show dev eth0 qdisc fq 8003: root refcnt 32 limit 10000p flow_limit 100p buckets 1024 quantum 3028 initial_quantum 15140 maxrate 8000Kbit Sent 16819357 bytes 11258 pkt (dropped 0, overlimits 0 requeues 0) rate 7831Kbit 653pps backlog 7570b 5p requeues 0 44 flows (43 inactive, 1 throttled), next packet delay 2977352 ns 0 gc, 0 highprio, 5545 throttled lpq83:~# tcpdump -p -i eth0 host lpq84 -c 12 09:02:52.079484 IP lpq83 > lpq84: . 1389536928:1389538376(1448) ack 3808678021 win 457 <nop,nop,timestamp 961812 572609068> 09:02:52.079499 IP lpq83 > lpq84: . 1448:2896(1448) ack 1 win 457 <nop,nop,timestamp 961812 572609068> 09:02:52.079906 IP lpq84 > lpq83: . ack 2896 win 16384 <nop,nop,timestamp 572609080 961812> 09:02:52.082568 IP lpq83 > lpq84: . 2896:4344(1448) ack 1 win 457 <nop,nop,timestamp 961815 572609071> 09:02:52.082581 IP lpq83 > lpq84: . 4344:5792(1448) ack 1 win 457 <nop,nop,timestamp 961815 572609071> 09:02:52.083017 IP lpq84 > lpq83: . ack 5792 win 16384 <nop,nop,timestamp 572609083 961815> 09:02:52.085678 IP lpq83 > lpq84: . 5792:7240(1448) ack 1 win 457 <nop,nop,timestamp 961818 572609074> 09:02:52.085693 IP lpq83 > lpq84: . 7240:8688(1448) ack 1 win 457 <nop,nop,timestamp 961818 572609074> 09:02:52.086117 IP lpq84 > lpq83: . ack 8688 win 16384 <nop,nop,timestamp 572609086 961818> 09:02:52.088792 IP lpq83 > lpq84: . 8688:10136(1448) ack 1 win 457 <nop,nop,timestamp 961821 572609077> 09:02:52.088806 IP lpq83 > lpq84: . 10136:11584(1448) ack 1 win 457 <nop,nop,timestamp 961821 572609077> 09:02:52.089217 IP lpq84 > lpq83: . ack 11584 win 16384 <nop,nop,timestamp 572609090 961821> Reported-by: NSteinar H.

Recently grabbed this report: https://bugzilla.redhat.com/show_bug.cgi?id=1005567 Of an issue in which the bonding driver, with an attached vlan encountered the following errors when bond0 was taken down and back up: dummy1: promiscuity touches roof, set promiscuity failed. promiscuity feature of device might be broken. The error occurs because, during __bond_release_one, if we release our last slave, we take on a random mac address and issue a NETDEV_CHANGEADDR notification. With an attached vlan, the vlan may see that the vlan and bond mac address were in sync, but no longer are. This triggers a call to dev_uc_add and dev_set_rx_mode, which enables IFF_PROMISC on the bond device. Then, when we complete __bond_release_one, we use the current state of the bond flags to determine if we should decrement the promiscuity of the releasing slave. But since the bond changed promiscuity state during the release operation, we incorrectly decrement the slave promisc count when it wasn't in promiscuous mode to begin with, causing the above error Fix is pretty simple, just cache the bonding flags at the start of the function and use those when determining the need to set promiscuity. This is also needed for the ALLMULTI flag CC: Jay Vosburgh <fubar@us.ibm.com> CC: Andy Gospodarek <andy@greyhouse.net> CC: Mark Wu <wudxw@linux.vnet.ibm.com> CC: "David S.

When TCP Small Queues was added, we used a sysctl to limit amount of packets queues on Qdisc/device queues for a given TCP flow. Problem is this limit is either too big for low rates, or too small for high rates. Now TCP stack has rate estimation in sk->sk_pacing_rate, and TSO auto sizing, it can better control number of packets in Qdisc/device queues. New limit is two packets or at least 1 to 2 ms worth of packets. Low rates flows benefit from this patch by having even smaller number of packets in queues, allowing for faster recovery, better RTT estimations. High rates flows benefit from this patch by allowing more than 2 packets in flight as we had reports this was a limiting factor to reach line rate.
