	Subject: [PATCH] ath9k: Fix bug in the way "bf_tx_aborted" of struct ath_buf is used
	Date:   Wed, 26 May 2010 19:06:53 -0700

	This bug was introduced by the following commit

		ath9k: Remove ATH9K_TX_SW_ABORTED and introduce a bool for this purpose

	Wrong buffer is checked for bf_tx_aborted field in ath_tx_num_badfrms(),
	this may result in a rate scaling with wrong feedback (number
	of unacked frames in this case). It is the last one in the chain
	of buffers for an aggregate frame that should be checked.

	Also it misses the initialization of this field in the buffer,
	this may lead to a situation where we stop the sw retransmission
	of failed subframes associated to this buffer.
