https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=192950 --- Comment #14 from Adrian Chadd <adrian@freebsd.org> --- Hi, So the tx path grabs the rate from the net80211 ratectl code. The link_quality table controls which rates are tried in which order, and I think it's _after_ the rate that is specified by the rate control code - but again, I can't be sure, because I haven't really sat down and figured out what the rate code does. Ie, if you do this: * link quality table has MCS0-7 in it; * you set a rate of MCS8 in the TX frame, btu also say "do link quality retries" then what happens. The default rate module for iwn is amrr. It's in net80211. That's what should be outputting debugging when you enable wlandebug +rate. -a -- You are receiving this mail because: You are the assignee for the bug.
