2008-01-28rt2x00: Always call ieee80211_stop_queue() when return NETDEV_TX_BUSYIvo van Doorn
Apparently it was possible that ieee80211_stop_queue() was not full while NETDEV_TX_BUSY was being reported back. I think that is what causing the WARN_ON(). This moves all calls to ieee80211_stop_queue() in rt2x00mac.c where it is easier to determine if the queue should be halted. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2008-01-28rt2x00: Add TX/RX frame dumping facilityIvo van Doorn
This adds TX/RX frame dumping capabilities through debugfs. The intention is that with this approach debugging of rt2x00 is simplified since _all_ frames going in and out of the device are send to debugfs as well along with additional information like the hardware descriptor. Based on the patch by Mattias Nissler. Mattias also has some tools that will make the dumped frames available to wireshark: http://www-user.rhrk.uni-kl.de/~nissler/rt2x00/ Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2008-01-28rt2x00: Add skb descriptorIvo van Doorn
Use the skb->cb field to add a frame description that can be used to transfer information passed each rt2x00 layer. This reduces the required arguments for rt2x00lib_write_tx_desc().

2008-01-28rt2x00: Replace DRV_NAME with KBUILD_MODNAMEIvo van Doorn
DRV_NAME was always set to the KBUILD_MODNAME value, lets clean everything up by removing DRV_NAME and just use KBUILD_MODNAME directly. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28rt2x00: Move duplicate code into rt2x00pci_txdone()Ivo van Doorn
rt2400pci, rt2500pci and rt61 require different txdone handling, but the code that pushes the frame upstream and cleans up the entry is identical to all of them. This will create the function rt2x00pci_txdone() to remove the duplicate code. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28rt2x00: Remove data_desc structureIvo van Doorn
Coverty indicated that data_desc with a single element array is bad coding style. This removes the structure and forces everybody to use __le32.

2008-01-16rt2x00: Fix ieee80211 payload alignmentIvo van Doorn
As Johannes Berg indicated, the NET_IP_ALIGN doesn't need to be used for ieee80211 frames. This means we can simplify the alignment calculation to just use the result of the header size modulus 4 as frame alignment. Furthermore we shouldn't use NET_IP_ALIGN in rt2x00usb because it could be 0 on some architectures and we absolutely need to have 2 bytes reserved for possible aligning.

2008-01-10rt2x00: Put 802.11 data on 4 byte boundaryIvo van Doorn

2007-10-10[PATCH] mac80211: revamp interface and filter configurationJohannes Berg
Drivers are currently supposed to keep track of monitor interfaces if they allow so-called "hard" monitor, and they are also supposed to keep track of multicast etc. This patch changes that, replaces the set_multicast_list() callback with a new configure_filter() callback that takes filter flags (FIF_*) instead of interface flags (IFF_*). For a driver, this means it should open the filter as much as necessary to get all frames requested by the filter flags. Accordingly, the filter flags are named "positively", e.g. FIF_ALLMULTI. Multicast filtering is a bit special in that drivers that have no multicast address filters need to allow multicast frames through when either the FIF_ALLMULTI flag is set or when the mc_count value is positive. At the same time, drivers are no longer notified about monitor interfaces at all, this means they now need to implement the start() and stop() callbacks and the new change_filter_flags() callback. Also, the start()/stop() ordering changed, start() is now called *before* any add_interface() as it really should be, and stop() after any remove_interface(). The patch also changes the behaviour of setting the bssid to multicast for scanning when IEEE80211_HW_NO_PROBE_FILTERING is set; the IEEE80211_HW_NO_PROBE_FILTERING flag is removed and the filter flag FIF_BCN_PRBRESP_PROMISC introduced. This is a lot more efficient for hardware like b43 that supports it and other hardware can still set the BSSID to all-ones.
