patch: update iwi(4)
Hi,
http://leaf.dragonflybsd.org/~hofmann/iwi_update.diff
is a patch to bring in the newest iwi(4) from FreeBSD.
It basically works and I can associate via wpa2.
There are some issues though that need to be resolved:
* Locking is done completely with lockmgr locks as it is done for
ath now. What is the plan about if_serializer?
I noticed that e.g. parent_updown() in ieee80211_proto.c calls
if_ioctl without if_serializer held. Does this mean that
if_serializer use is deprecated?
* It still uses our old firmware API via wrapper functions, as I
didn't know how to create the firmware modules needed with the new API.
Therefore the patch brings kern_firmware.c back into the kernel
build, but all this can easily be switched to the new API.
* sysctl's are not removed on module unload, so when unloading/loading
I get warnings about reusing sysctl leafs. I didn't find the
relevent code in the other drivers, so maybe I'm missing something
here.
* The alloc_unr()/free_unr() stuff is just commented out. Are there
any plans to bring in this API from FreeBSD?
