A bunch of information that is put into the radiotap header is put inside struct ieee80211_rx_stats when the driver passes the frame to the ieee80211 layer. I think it is a better idea to expand ieee80211_rx_stats to include all information necessary for filling in a radiotap header, and let the ieee80211 tack on the header. I would prefer either that or giving drivers access to the generic monitor mode path so frames can be passed to userspace ASAP. Also, we probably want an ioctl or some way to switch between raw ieee80211 frames and radiotap headers. -Michael Wu |

Opps, didn't notice this last time. Disassoc/deauth do not have any info
elements. My patch did not include the zero length array at the end of this
frame.
Otherwise, it looks pretty good..
Thanks,

I'm pretty sure I had typed it in during the original commit; now that I've rebased 3 times, I don't actually have the original commit logs though -- so not sure if I just don't remember, or what. The GIT log in the bughost.org repository does list him as the author. The git-format-patch-script didn't seem to make emails with legible author information though (it stuck the author information in between the first line of the commit message and the rest of the message) James |

Per the conversations with folks at OLS, the QoS layer in 802.11
drivers can now result in NETDEV_TX_BUSY being returned when the queue
a packet is targetted for is full.
To implement this, ieee80211_xmit will now call the driver's
is_queue_full to determine if the current priority queue is full. If
so, NETDEV_TX_BUSY is returned to the kernel and no processing is done
on the frame.

This fixes several things:
1. TKIP encryption
Originally, TKIP encryption issues msdu + mpdu encryption on every
fragment. Change the behavior to msdu encryption on the whole
packet, then mpdu encryption on every fragment.
2. Avoid repeated fragmentation when !host_encrypt.
We only need do fragmentation when using host encryption. Otherwise
we only need pass the whole packet to driver, letting driver do the
fragmentation.
3. change the txb->payload_size to correct value
FW will use this value to determine whether to do fragmentation. If
we pass the wrong value, fw may cut on the wrong bound which will
make decryption fail when we do host encryption.

Added ieee80211_tx_frame to convert generic 802.11 data frames into
txbs for transmission.
Added several purpose specific callbacks (handle_assoc, handle_auth,
etc.) which the driver can register with for being notified on
reception of various frame elements.

Renamed ieee80211_hdr to ieee80211_hdr_4addr and modified ieee80211_hdr
to just contain the frame_ctrl and duration_id.
Changed uses of ieee80211_hdr to ieee80211_hdr_4addr or
ieee80211_hdr_3addr based on what was expected for that portion of code.
Signed-off-by: James Ketrenos <jke...@li...>
NOTE: This requires changing driver's that use ieee80211_hdr to use the
appropriate structure.
