2016-05-09net: dsa: mv88e6xxx: factorize GLOBAL_CONTROL_2 setupVivien Didelot
All switch models setup the GLOBAL_CONTROL_2 register with slightly differences. Since the cascade mode is valid even in a single chip setup, factorize such configuration. Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-05-09net: dsa: mv88e6xxx: factorize GLOBAL_MONITOR_CONTROL setupVivien Didelot
All switch drivers configure the GLOBAL_MONITOR_CONTROL register with slightly changes. Assume the setup of the upstream port, and configure it as the port to which ingress and egress and ARP monitor frames are to be sent.

2016-05-09net: dsa: mv88e6131: drop VLAN Ethertype setupVivien Didelot
The 6131 switch models have a Core Tag Type register. Their setup code is setting it to 0x8100, which is the reset default. Drop this specific part which is correctly configured on reset anyway.

2016-05-09net: dsa: mv88e6xxx: factorize GLOBAL_CONTROL setupVivien Didelot
All switch models configure the GLOBAL_CONTROL register with slightly differences. Discarding packets with excessive collisions (GLOBAL_CONTROL_DISCARD_EXCESS) is specific to 6352 and similar switches, and setting a maximum frame size (GLOBAL_CONTROL_MAX_FRAME_1632) is specific to 6185 and similar switches. As we are centralizing the chips setup, skip these settings and don't discard any frames yet, until we found out that such discarding by the hardware is necessary. Assume a common setup to enable the PHY Polling Unit if present, don't discard any packets, and mask all interrupt sources. Tested on 88E6352 and 88E6185.

2016-05-09can: janz-ican3: error handling for CAL/CANopen firmwareAndreas Gröger
My patch of May 2015 was missing the changed handling of error indications. With CAL/CANopen firmware the NMTS-SlaveEventIndication must be used instead of CAN-EventIndication. An appropriate slave node must be configured to report the errors. In our department (about 15 development systems with Janz ICAN3- modules with firmware 1.48, my system also with firmware ICANOS 1.35) we use the driver with this patch for about one year: no known problems.

2016-05-09can: fix handling of unmodifiable configuration optionsOliver Hartkopp
As described in 'can: m_can: tag current CAN FD controllers as non-ISO' (6cfda7fbebe) it is possible to define fixed configuration options by setting the according bit in 'ctrlmode' and clear it in 'ctrlmode_supported'. This leads to the incovenience that the fixed configuration bits can not be passed by netlink even when they have the correct values (e.g. non-ISO, FD). This patch fixes that issue and not only allows fixed set bit values to be set again but now requires(!) to provide these fixed values at configuration time. A valid CAN FD configuration consists of a nominal/arbitration bittiming, a data bittiming and a control mode with CAN_CTRLMODE_FD set - which is now enforced by a new can_validate() function. This fix additionally removed the inconsistency that was prohibiting the support of 'CANFD-only' controller drivers, like the RCar CAN FD. For this reason a new helper can_set_static_ctrlmode() has been introduced to provide a proper interface to handle static enabled CAN controller options.

2016-05-08fq_codel: add memory limitation per queueEric Dumazet
On small embedded routers, one wants to control maximal amount of memory used by fq_codel, instead of controlling number of packets or bytes, since GRO/TSO make these not practical. Assuming skb->truesize is accurate, we have to keep track of skb->truesize sum for skbs in queue. This patch adds a new TCA_FQ_CODEL_MEMORY_LIMIT attribute. I chose a default value of 32 MBytes, which looks reasonable even for heavy duty usages. (Prior fq_codel users should not be hurt when they upgrade their kernels) Two fields are added to tc_fq_codel_qd_stats to report : - Current memory usage - Number of drops caused by memory limits # tc qd replace dev eth1 root est 1sec 4sec fq_codel memory_limit 4M .. # tc -s -d qd sh dev eth1 qdisc fq_codel 8008: root refcnt 257 limit 10240p flows 1024 quantum 1514 target 5.0ms interval 100.0ms memory_limit 4Mb ecn Sent 2083566791363 bytes 1376214889 pkt (dropped 4994406, overlimits 0 requeues 21705223) rate 9841Mbit 812549pps backlog 3906120b 376p requeues 21705223 maxpacket 68130 drop_overlimit 4994406 new_flow_count 28855414 ecn_mark 0 memory_used 4190048 drop_overmemory 4994406 new_flows_len 1 old_flows_len 177 Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: Jesper Dangaard Brouer <brouer@redhat.com> Cc: Dave Täht <dave.taht@gmail.com> Cc: Sebastian Möller <moeller0@gmx.de> Signed-off-by: David S.
