* Revert if_oqdrops accounting changes done in kernel, per request from mpi@.uebayasi2015-10-051-3/+2
| | | | | | | | | | | | | (Especially adding IF_DROP() after IFQ_ENQUEUE() was completely wrong because IFQ_ENQUEUE() already does it. Oops.) After this revert, the situation becomes: - if_snd.ifq_drops is incremented in either IFQ_ENQUEUE() or IF_DROP(), but it is not shown to userland, and - if_data.ifi_oqdrops is shown to userland, but it is not incremented by anyone.

* Make room for media types of the future. Extend the ifmedia word to 64 bits.stsp2015-09-112-13/+15
| | | | | | | | | | | | | | | | 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

* remove the second void * argument on tasks.dlg2015-01-271-4/+4
| | | | | | | | | | | | | | | | | | | | | when workqs were introduced, we provided a second argument so you could pass a thing and some context to work on it in. there were very few things that took advantage of the second argument, so when i introduced pools i suggested removing it. since tasks were meant to replace workqs, it was requested that we keep the second argument to make porting from workqs to tasks easier. now that workqs are gone, i had a look at the use of the second argument again and found only one good use of it (vdsp(4) on sparc64 if you're interested) and a tiny handful of questionable uses. the vast majority of tasks only used a single argument. i have since modified all tasks that used two args to only use one, so now we can remove the second argument. so this is a mechanical change. all tasks only passed NULL as their second argument, so we can just remove it. ok krw@

* Change rssi passed to ifconfig(8) to a signed value to fix printing signalsthen2015-01-091-3/+3
| | | | | | | | | | | strengths on 802.11 interfaces. ok stsp@ Power on wireless interfaces is usually scaled in dBm. rssi (received signal strength) is expected to be a -ve dBm values (i.e. [much] <1mW). Some (though not all!) drivers store this as negative values, so it needs to be passed to ifconfig that way for printing, not cast to an unsigned value. Valid range is something like -40 to -90dBm, so the range available with a signed char is reasonable whether it's stored as a +ve or -ve number.

* Fix wrong IEEE 802.11 ioctl's:zhuk2014-08-241-2/+2
| | | | | | | | | | | | | | | * SIOCG80211ALLNODES operates on struct ieee80211_nodereq_all, not struct ieee80211_nodereq. * Six SIOC* from wi(4) were using same codes with generic parts of IEEE 802.11 framework. Things worked due to the fact that size of data struct being passed is encoded in actual SIOC*, too. This commit means that ifconfig and some ports will need to be rebuilt, if any of affected SIOC* codes is used. Port bumps to follow.
