It isn't. AFAIR, Robert promised to remove all !MPSAFE NIC drivers before
RELENG_7.
Other than performance issues, what's the point of doing this?
To me that sounds like we'd lose all of usb ethernet as it stands. I'm fine
with fixing usb ethernet, but not under some thread-model of developement.
You have been pointed to the USB stack rewrite for 7.x at least three times in
the last 24 hours. Getting developers involved in reviewing and testing this
work would be very useful.
The point of removing compatibility code for non-MPSAFE drivers is to remove
compatibility code for non-MPSAFE drivers. For entertainment value, grep -i
giant in src/sys/net. We go through some odd contortions to acquire Giant
where it is needed, defer work to run under Giant, and so on.
