* add support for multiple transmit ifqueues per network interface.dlg2017-01-241-7/+8
| | | | | | | | | | | | | | | | | | | | | | | an ifq to transmit a packet is picked by the current traffic conditioner (ie, priq or hfsc) by providing an index into an array of ifqs. by default interfaces get a single ifq but can ask for more using if_attach_queues(). the vast majority of our drivers still think there's a 1:1 mapping between interfaces and transmit queues, so their if_start routines take an ifnet pointer instead of a pointer to the ifqueue struct. instead of changing all the drivers in the tree, drivers can opt into using an if_qstart routine and setting the IFXF_MPSAFE flag. the stack provides a compatability wrapper from the new if_qstart handler to the previous if_start handlers if IFXF_MPSAFE isnt set. enabling hfsc on an interface configures it to transmit everything through the first ifq. any other ifqs are left configured as priq, but unused, when hfsc is enabled. getting this in now so everyone can kick the tyres. ok mpi@ visa@ (who provided some tweaks for cnmac).

* replace IFF_OACTIVE manipulation with mpsafe operations.dlg2015-11-251-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | there are two things shared between the network stack and drivers in the send path: the send queue and the IFF_OACTIVE flag. the send queue is now protected by a mutex. this diff makes the oactive functionality mpsafe too. IFF_OACTIVE is part of if_flags. there are two problems with that. firstly, if_flags is a short and we dont have any MI atomic operations to manipulate a short. secondly, while we could make the IFF_OACTIVE operates mpsafe, all changes to other flags would have to be made safe at the same time, otherwise a read-modify-write cycle on their updates could clobber the oactive change. instead, this moves the oactive mark into struct ifqueue and provides an API for changing it. there's ifq_set_oactive, ifq_clr_oactive, and ifq_is_oactive. these are modelled on ifsq_set_oactive, ifsq_clr_oactive, and ifsq_is_oactive in dragonflybsd. this diff includes changes to all the drivers manipulating IFF_OACTIVE to now use the ifsq_{set,clr_is}_oactive API too. ok kettenis@ mpi@ jmatthew@ deraadt@

* In bge_reset(), after figuring out which register access routines to usemiod2015-11-101-2/+2
| | | | | | | | | | | depending upon the chip capabilities, use it everywhere instead of hardcoding one call to bge_writemem_ind() by mistake; this unbreaks the BCM5704 A3 found on some xserve G5 (RackMac3,1). Also tested on a few other bge(4) chip models by jmatthew@ (5703X, 5714), mpi@ (5780), naddy@ (5761) and me (5701). ok dlg@

* Move bge rxeof and txeof outside the kernel lock.jmatthew2015-10-191-109/+92
| | | | | | | | | | | | | | | | To make rxeof safe, use a separate ring refill timeout for each ring. We activate the refill timeout for a ring when it's too empty to receive packets, which ensures we won't attempt to refill it from interrupt context. To make txeof safe, remove the list of dma maps and just allocate maps based on the ring slots occupied by the packet, and use atomic operations to adjust bge_txcnt. Rework some parts of the txeof and start loops so that we only adjust bge_txcnt after exiting the loop, and only take actions such as setting or clearing OACTIVE based on the final value. tested on 5703, 5714, 5721 by me, 5753 by semarie@, 5761 by naddy@, and also in snapshots for a while ok mpi@, dlg@

* sending a heavily fragmented packet will cause the bus_dmamap_loaddlg2014-07-031-3/+14
| | | | | | | | | | | | | | | | | | in bge_encap to fail because the dmamap lacks space, not necessarily because the ring is full. however, bge_encap failure sets the OACTIVE flag on the interface and keeps the packet at the start of the send queue. the next time we try to fill the tx ring we'll try to load the same packet and fail. an empty tx ring means bge_txeof hasnt got anything which is where the OACTIVE condition is cleared. this diff adds handling of fragmented packets via m_defrag. this might fix the issues landry@ has been complaining about on his bulk build machines. i can reproduce the above problem in contrived circumstances here and this diff fixes it, so its going in so landry@ is forced to test it.

* Revert rev 1.348 and disable IPv6 TCP checksum offload for the time being.brad2014-02-241-3/+1
| | | | | | | | | | It has been reported that the offload support is not working properly with some of the newer ASICs, specifically BCM57780 and BCM57765. It is unknown what the issue is whether it could be hw, the driver or the stack; so to be on the safe side it is being disabled all together until the issue can be investigated further. ok deraadt@
