Subject: [PATCH 16/19] rt2800: use TXOP_BACKOFF for probe frames
|
|
|
|
Even if we do not set AMPDU bit in TXWI, device still can aggregate
|
|
frame and send it with rate not corresponding to requested. That mean
|
|
we can do not sent probe frames with requested rate. To prevent that
|
|
use TXOP_BACKOFF for probe frames.
