For Gigabit Ethernet version of AR816x, AR813x/AR815x except L1D controller, use vendor recommended ASPM parameters. While here, increase alc_dma_burst array size. Broken H/W can return bogus value in theory From Brad.

| | | | | | | Some of the flag and oactive handling bits and alc_stop_queue() were mismerged. Pointed out by Brad, thanks!

* 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@
* rework the start routines to avoid IF_PREPEND.dlg2015-11-091-33/+19
| | | | | | | | | | | | IF_PREPEND assumes the underlying send queue is priq, while hfsc may be enabled on it. the previous code pattern to DEQUEUE, try and encap the mbuf on the ring, and if that failed cos there was no space it would PREPEND it. now it checks for space on the ring before it attempts to DEQUEUE. failure to encap means the mbuf is now unconditionally dropped.

* Make room for media types of the future. Extend the ifmedia word to 64 bits.stsp2015-09-111-3/+3
| | | | | | | | | | | | | | | | This changes numbers of the SIOCSIFMEDIA and SIOCGIFMEDIA ioctls and grows struct ifmediareq. Old ifconfig and dhclient binaries can still assign addresses, however the 'media' subcommand stops working. Recompiling ifconfig and dhclient with new headers before a reboot should not be necessary unless in very special circumstances where non-default media settings must be used to get link and console access is not available. There may be some MD fallout but that will be cleared up later. ok deraadt miod with help and suggestions from several sharks attending l2k15

* Fix up alc_encap() / alc_start():kevlo2011-09-131-34/+23
| | | | | | | | | | | | | | | | | | - Remove unnecessary nsegs variable from alc_encap() and use map->dm_nsegs. Also remove unnecessary FreeBSD check for 0 DMA segments check. - Remove printfs in alc_encap() failure paths that shouldn't be there. - Add missing IF_PREPEND() from failure path coming off of alc_encap() within alc_start(). - Fix error handling within alc_encap(). Previously alc_encap() was attempting to unload a DMA map upon failure from bus_dmamap_load_mbuf() even though one wasn't loaded at that point and then always forcing mbufs through the EFBIG path. Tested by Gabriel Linder. From Brad

Previously it failed to re-establish link when the cable was plugged in such that it required turning the interface down and then up to make it work. This was caused by incorrectly programmed hibernation parameters. Further details regarding PHY setup are necessary to be able to re-enable this feature.
