This moves the PnP OID definitions to the RNDIS_* namespace and puts them in the next falling slot in the list. Oh, the comment above the PnP defines was referring to some obsolete or out-of-tree driver so removed it, and removed my own comments telling where each header segment came from as well, we have moved everything around by this point anyway.

The NDIS_*-prefixed packet types have equivalent RNDIS_*- prefixed types, besides nothing in the kernel use these defines. Signed-off-by:

Let's have a unified table of RNDIS media. We used to have a similar table with NDIS_* prefix from the gadget driver, but since we're only using RNDIS in the kernel (IIRC NDIS, non-remote, is for the windows- internal network drivers so what do we care) let's prefix everything with RNDIS. Some of the definitions were conflicting, in one of the defines 0x0B is bearer "CO WAN" and in two others "BPC". Well I took the majority vote. Two definition of medium 0x09 calls it "wireless WAN" but one vote for "wireless LAN" but in this case I am sticking with the minority, "Wide Area Network" does not make much sense in this case as far as I can tell. NOTE: latin singular and plural is so screwed up in these defines that it makes my eyes bleed. But I will not attempt to submit a patch converting all use of _MEDIA_ to _MEDIUM_ while I can probably tell from the semantics of the code that RNDIS_MEDIA_STATE_CONNECTED is most probably (erroneously) referring to a singular, unless it can return an array of connected media. I suspect these erroneous plurals are used in documentation and such so I don't want to mess around with things for no functional change. Signed-off-by:

The 802_* network OIDs were duplicated, so let's merge them and use the RNDIS_* prefixed definitions from the hyperV driver. Signed-off-by:

Linus Walleij authored
The RNDIS protocol contains a vast number of Object ID:s (OIDs). The current definitions had multiple definitions of these ID:s, let's use the nicely RNDIS_*-prefixed defines from the HyperV implementation, rename everywhere they're used, and copy+rename the few that were missing from this list of objects.

Linus Walleij authored
The RNDIS status codes are redefined with much stranged ifdeffery and only one of these codes was used in the hyperv driver, and there it is very clearly referring to the RNDIS variant, not some other status. So clarify this by explictly using the RNDIS_* prefixed status code in the hyperv drivera and delete the duplicate defines. Reviewed-by:

Linus Walleij authored
As a first step to consolidate the RNDIS implementations, break out a common file with all the #defines and move it to <linux/rndis.h>. This also deletes the immediate duplicated defines in the <linux/rndis.h> file that yields a lot of compilation warnings. Reviewed-by:
-
Linus Walleij authored
The header file <linux/usb/rndis_host.h> used a number of #defines that included the cpu_to_le32() macro to assure the result will be in LE endianness. Inlining this into the code instead of using it in the code definitions yields consolidation opportunities later on as you will see in the following patches. The individual drivers also used local defines - all are switched over to the pattern of doing the conversion at the call sites instead. Signed-off-by:

batman-adv would forward OGMs from non-besthops while replacing the the TQ and TTL values with the values from the best hop. In certain corner cases this leads to a temporary routing loop. This patch changes this behavior: Only packets from best next hops are forwarded - TQ and TTL values won't be replaced anymore. However, the protocol needs to rebroadcast OGMs from single hop neighbors regardless of whether or not they are the best hop. To handle this case a new flag is introduced to alert neighboring nodes about the forwarded OGM that is not from my best next hop. It is to be discarded by all nodes except for the one originating the OGM. Signed-off-by:

This allows us to easily add a sysfs parameter for an unsigned int later, which is not for a batman mesh interface (e.g. bat0), but for a common interface instead. It allows reading and writing an atomic_t in hard_iface (instead of bat_priv compared to the mesh variant). Developed by Linus during a 6 months trainee study period in Ascom (Switzerland) AG.

An implementation of CoDel AQM, from Kathleen Nichols and Van Jacobson. http://queue.acm.org/detail.cfm?id=2209336 This AQM main input is no longer queue size in bytes or packets, but the delay packets stay in (FIFO) queue. As we don't have infinite memory, we still can drop packets in enqueue() in case of massive load, but mean of CoDel is to drop packets in dequeue(), using a control law based on two simple parameters : target : target sojourn time (default 5ms) interval : width of moving time window (default 100ms) Based on initial work from Dave Taht. Refactored to help future codel inclusion as a plugin for other linux qdisc (FQ_CODEL, ...), like RED. include/net/codel.h contains codel algorithm as close as possible than Kathleen reference. net/sched/sch_codel.c contains the linux qdisc specific glue. Separate structures permit a memory efficient implementation of fq_codel (to be sent as a separate work) : Each flow has its own struct codel_vars. timestamps are taken at enqueue() time with 1024 ns precision, allowing a range of 2199 seconds in queue, and 100Gb links support. iproute2 uses usec as base unit. Selected packets are dropped, unless ECN is enabled and packets can get ECN mark instead. Tested from 2Mb to 10Gb speeds with no particular problems, on ixgbe and tg3 drivers (BQL enabled). Usage: tc qdisc ... codel [ limit PACKETS ] [ target TIME ] [ interval TIME ] [ ecn ] qdisc codel 10: parent 1:1 limit 2000p target 3.0ms interval 60.0ms ecn Sent 13347099587 bytes 8815805 pkt (dropped 0, overlimits 0 requeues 0) rate 202365Kbit 16708pps backlog 113550b 75p requeues 0 count 116 lastcount 98 ldelay 4.3ms dropping drop_next 816us maxpacket 1514 ecn_mark 84399 drop_overlimit 0 CoDel must be seen as a base module, and should be used keeping in mind there is still a FIFO queue. So a typical setup will probably need a hierarchy of several qdiscs and packet classifiers to be able to meet whatever constraints a user might have. One possible example would be to use fq_codel, which combines Fair Queueing and CoDel, in replacement of sfq / sfq_red. Signed-off-by:

Class bytes/packets stats can be misleading because they are updated in enqueue() while packet might be dropped later. We already fixed all qdiscs but sch_atm. This patch makes the final cleanup. class rate estimators can now match qdisc ones. Signed-off-by:

Calling pci_disable_sriov() while VFs are assigned to VMs causes kernel panic. This patch uses PCI_DEV_FLAGS_ASSIGNED bit state of the VF's pci_dev to avoid this. Also, the unconditional function reset cmd issued on a PF probe can delete the VF configuration for the previously enabled VFs. A scratchpad register is now used to issue a function reset only when needed (i.e., in a crash dump scenario.) Signed-off-by:

If enabled, L2TP data packets have sequence numbers which a receiver can use to drop out of sequence frames or try to reorder them. The first frame has sequence number 0, but the L2TP code currently expects it to be 1. This results in the first data frame being handled as out of sequence. This one-line patch fixes the problem.

When L2TP data packet reordering is enabled, packets are held in a queue while waiting for out-of-sequence packets. If a packet gets lost, packets will be held until the reorder timeout expires, when we are supposed to then advance to the sequence number of the next packet but we don't currently do so. As a result, the data channel is stuck because we are waiting for a packet that will never arrive - all packets age out and none are passed. The fix is to add a flag to the session context, which is set when the reorder timeout expires and tells the receive code to reset the next expected sequence number to that of the next packet in the queue. Tested in a production L2TP network with Starent and Nortel L2TP gear. Signed-off-by:
