| | | | | | | | | | | | | | | | | | | NET_NEEDS_GIANT. netatm has been disconnected from the build for ten months in HEAD/RELENG_7. Specifics: - netatm include files - netatm command line management tools - libatm - ATM parts in rescue and sysinstall - sample configuration files and documents - kernel support as a module or in NOTES - netgraph wrapper nodes for netatm - ctags data for netatm. - netatm-specific device drivers.

* Don't remove the first mbuf in the chain if it got empty.harti2004-02-211-7/+6
| | | | | | | | This removes the packet header in certain cases which later on will give panic. Clarify what the atm_intr expects in the comment and de-obscurify the code a little bit by replacing the portability macros with the BSD names. The code isn't maintained externally anymore so there's no point in keeping the extra level of obscurity.

* Remove the zone limits for all the zones used in the ATM code.harti2003-07-221-2/+0
| | | | | | | | | | | These were a left over from when the private memory pools were converted to use uma zones. The limit of UMA zones, however, works differently. When a zone is limited to only one or two pages than, on multi-cpu systems, processes can get stuck on the zonelimit, because all remaining free items are in caches of other CPUs. Also add rudimentary error handling in some places (panic) when a zone cannot be created.

* Update netisr handling; Each SWI now registers its queue, and all queuejlemon2003-03-041-43/+28
| | | | | | | | | | drain routines are done by swi_net, which allows for better queue control at some future point. Packets may also be directly dispatched to a netisr instead of queued, this may be of interest at some installations, but currently defaults to off.

* Lock down the network interface queues. The queue mutex must be obtainedjlemon2000-11-251-0/+1
| | | | | | | | | | | | | | before adding/removing packets from the queue. Also, the if_obytes and if_omcasts fields should only be manipulated under protection of the mutex. IF_ENQUEUE, IF_PREPEND, and IF_DEQUEUE perform all necessary locking on the queue. An IF_LOCK macro is provided, as well as the old (mutex-less) versions of the macros in the form _IF_ENQUEUE, _IF_QFULL, for code which needs them, but their use is discouraged. Two new macros are introduced: IF_DRAIN() to drain a queue, and IF_HANDOFF, which takes care of locking/enqueue, and also statistics updating/start if necessary.
