Message-ID: <CAA93jw5VqHH4AX58MS+aMMo0EyogGmkn2V2PpLDYAec3fvE13g@mail.gmail.com> (raw)
I don't see a reason to have ATH_MAX_SW_RETRIES of 30. ?
ATH_TXMAXTRY appears to be unused.
I am also sufficiently bugged at the VI queues behavior to go and fix
it finally (which also ties into a few other things)
