Linux driver code quality was then (i.e. about 13 or so years ago when the decision was being made, before my time), and is now, kind of atrocious, partially because so much of it is vendors just dumping code into the kernel and it usually "works", though often unreliably or with poor performance... I know you are being rather vague here about what kind of "alignment" you are talking about. If you mean incremental changes to the net80211 stack to get it to look more like mac80211 or something, I don't really have much of an opinion there (Haiku uses net80211 wholesale, with of course an ieee80211_haiku.cpp to interface with our own systems, so any changes will get pulled in without much effort.) But if you mean moving WiFi onto linuxkpi ... well ... we'd be sorry to see the old stack go, to say the least... As for collaboration: The only driver bugfixes we have (almost entirely made by me) were already upstreamed into FreeBSD one way or another, and I continue to remain diligent about that. (IIRC at the point we upgraded to FreeBSD 11 drivers, there were some broken iwn chipsets with trivial fixes that apparently nobody had noticed on FreeBSD, so our install base may have more variance in WiFi cards than FreeBSD, by some metric!) We don't have the manpower to really contribute much to WiFi drivers themselves. Financial support would be another matter; if we had a way to specifically earmark funding for WiFi, and only WiFi (or at least, WiFi plus less-maintained ethernet drivers), I could petition our Inc. to donate, and the community at large, too. It wouldn't be a lot, but if you are only part-time anyway, perhaps a modest amount could go a long way, anyway. -waddlesplash _______________________________________________ freebsd-wireless@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-wireless To unsubscribe, send any mail to "freebsd-wireless-unsubscr...@freebsd.org"
