Subject: carl9170 firmware: remove BAR->BA clutter
X-Git-Tag: 1.9.6~17
X-Git-Url: https://jxself.org/git/?p=carl9170fw.git;a=commitdiff_plain;h=2bd700be49afc4c07cf45d0b537980e35322173b

carl9170 firmware: remove BAR->BA clutter

No need for a dynamic rate adjustment for this special
case of outgoing BAs. The original firmware didn't care
much for them either.
