| | | | | | | | | | | | Add new tunable 'net.link.ifqmaxlen' to set default send interface queue length. The default value for this parameter is 50, which is quite low for many of today's uses and the only way to modify this parameter right now is to edit if_var.h file. Also add read-only sysctl with the same name, so that it's possible to retrieve the current value. Notes: svn path=/stable/7/; revision=215368

RIght now, no drivers are MPSAFE, though a few will be changed in the coming week as this work settles down. The driver API has changed, so all CAM drivers will need to be recompiled. The userland API has not changed, so tools like camcontrol do not need to be recompiled. Notes: svn path=/head/; revision=168752

| | | | | | | | | | | | | | | | | IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to ifnet.if_drv_flags. Device drivers are now responsible for synchronizing access to these flags, as they are in if_drv_flags. This helps prevent races between the network stack and device driver in maintaining the interface flags field. Many __FreeBSD__ and __FreeBSD_version checks maintained and continued; some less so.

* Stop embedding struct ifnet at the top of driver softcs. Instead theBrooks Davis2005-06-101-21/+25
| | | | | | | | | | | | | | | | | | | | | | | struct ifnet or the layer 2 common structure it was embedded in have been replaced with a struct ifnet pointer to be filled by a call to the new function, if_alloc(). The layer 2 common structure is also allocated via if_alloc() based on the interface type. It is hung off the new struct ifnet member, if_l2com. This change removes the size of these structures from the kernel ABI and will allow us to better manage them as interfaces come and go. Other changes of note: - Struct arpcom is no longer referenced in normal interface code. Instead the Ethernet address is accessed via the IFP2ENADDR() macro. To enforce this ac_enaddr has been renamed to _ac_enaddr. - The second argument to ether_ifattach is now always the mac address from driver private storage rather than sometimes being ac_enaddr.

* In ppsintr, we needed ppsdev to get to the softc and nothing else.Warner Losh2005-04-141-11/+7
| | | | | | | | | | | | | | | | | | Save a memory dereference in the ISR by passing this in directly. Calling pps_capture is MP safe for all other operations on struct pps_state, so there's no need to aquire the lock before we do this, even from a fast ISR. Avoid dereferencing sc->ppbus until after pps_capture is called as well. These actions reduce somewhat the cache effects that cause variance in interrupt times. On an especially slow test machine (300MHz Cyrix GXm), this reduces the interrupt latency about about 10% (from 21us to 19us) and helps a little with the variance (although most of the variance seems to be caused by lots of interrupt masking). This also happens fixes one or two of bde's style issues. Notes: svn path=/head/; revision=145075

* Apply error and success logic consistently to the function netisr_queue() andAndre Oppermann2004-08-271-2/+2
| | | | | | | | | | | | | | | | | | | | | its users. netisr_queue() now returns (0) on success and ERRNO on failure. At the moment ENXIO (netisr queue not functional) and ENOBUFS (netisr queue full) are supported. Previously it would return (1) on success but the return value of IF_HANDOFF() was interpreted wrongly and (0) was actually returned on success. Due to this schednetisr() was never called to kick the scheduling of the isr. However this was masked by other normal packets coming through netisr_dispatch() causing the dequeueing of waiting packets.
