* Make sure that we call if_free(ifp) after bus_teardown_intr. Since weWarner Losh2005-09-191-1/+1
| | | | | | | | | | could get an interrupt after we free the ifp, and the interrupt handler depended on the ifp being still alive, this could, in theory, cause a crash. Eliminate this possibility by moving the if_free to after the bus_teardown_intr() call. Notes: svn path=/head/; revision=150306

* if_ral_pccard does not depend on pccard module directly, but ratherWarner Losh2005-08-221-1/+0
| | | | | | | | | | depends, like all other pccard drivers, indirectly through kobj on pccard. Therefore, it is not appropriate to force pccard to be loaded when if_ral.ko is loaded. This makes it possible to load if_ral w/o loading pccard.ko on, eg, pci only systems. Notes: svn path=/head/; revision=149359

* Clarify/fix handling of the current channel:Sam Leffler2005-08-101-7/+8
| | | | | | | | | | | | | | | | | | | | | | o add ic_curchan and use it uniformly for specifying the current channel instead of overloading ic->ic_bss->ni_chan (or in some drivers ic_ibss_chan) o add ieee80211_scanparams structure to encapsulate scanning-related state captured for rx frames o move rx beacon+probe response frame handling into separate routines o change beacon+probe response handling to treat the scan table more like a scan cache--look for an existing entry before adding a new one; this combined with ic_curchan use corrects handling of stations that were previously found at a different channel o move adhoc neighbor discovery by beacon+probe response frames to a new ieee80211_add_neighbor routine Reviewed by: avatar Tested by: avatar, Michal Mertl MFC after: 2 weeks Notes: svn path=/head/; revision=148936
* Propagate rename of IFF_OACTIVE and IFF_RUNNING to IFF_DRV_OACTIVE andRobert Watson2005-08-092-13/+14
| | | | | | | | | | | | | | | | | 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.

* o Fix a write mbuf-after-free bug. The duration field of the 802.11 headerDamien Bergamini2005-06-291-9/+23
| | | | | | | | | | | | | | was written in the old fragmented mbuf chain instead of the defragmented one. Thus, the duration field of outgoing frames was incorrect. o Only call m_defrag() if the mbuf fragmentation threshold is greater than what is currently supported by the driver.

* Stop embedding struct ifnet at the top of driver softcs. Instead theBrooks Davis2005-06-102-5/+11
| | | | | | | | | | | | | | | | | | | | | | | 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.
