The mac80211 tx queues and brcmsmac DMA fifos both map directly to AC levels. Therefore it's much more straightforward to queue tx frames and choose the tx fifo based on the mac80211 queue instead of mapping 802.1D priority tags to precedence levels then back to AC levels. mac80211 already maps the 802.1D levels to the appropriate AC levels and queues management frames at the maximum priority, so the results should be identical. One functional change resulting from this patch is that AMPDU retries no longer get a priority boost to queue them ahead of packets with the same priority already in the tx queue. This behavior will be restored (in effect at least) in a later patch when the tx queue is removed. Signed-off-by:

According to the comments this "reduces rate lag," but in reality the only way this value is used is for determining whether or not any frames remain to be transmitted. Therefore there's no reason for AMPDU packets to receive any weighting. Signed-off-by:

AMPDU session allows MPDUs to be temporarily queued until either a full AMPDU has been collected or circumstances dictate that transmission should start with a partial AMPDU. Packets are added to the session by calling brcms_c_ampdu_add_frame(). brcms_c_ampdu_finalize() should be called to fix up the tx headers in the first and last packet before adding the packets to the DMA ring. brmcs_c_sendampdu() is converted to using AMPDU sessions. This patch has no real value on it's own, but is needed in preparation for elimination of the tx packet queue from brcmsmac. Signed-off-by:

Samuel says: "This is the 2nd NFC pull request for 3.8. With this one we have: - A few HCI improvements in preparation for an upcoming HCI chipset support. - A pn544 code cleanup after the old driver was removed. - An LLCP improvement for notifying user space when one peer stops ACKing I frames."

Drivers are allowed to modify the sent skb and thus we need to make a copy of it before passing it to the driver. Without this fix, LLCP Tx skbs were not queued properly as the ptype check was failing due to e.g. the pn533 driver skb_pushing the Tx skb. Reported-by:

In some cases, pre-opened pipes don't stay open when a clear all pipes command is sent. They stay created however. Therefore, one can never assume that such a pipe is already open. As re-opening a pipe seems not to be a problem, we do that now. Signed-off-by:

The IF event need special care. It can be either an ADD, DEL, or CHANGE. For an ADD we need to call brcmf_add_if() before the event handler call. Upon a DEL we need to call brcmf_del_if() after the event handler call. CHANGE does not require special attention. Reviewed-by:

The brcmf_add_if() function had a struct device as parameter to accomodate the bus specific code to use this function.
