| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Section 9.23.3.5 of IEEE 80211s standard describes the protection rules for HT mesh STA in a MBSS. Three HT protection modes are supported for now: non-HT mixed mode - is selected if any non-HT peers are present in our MBSS. 20MHz-protection mode - is selected if all peers in our 20/40MHz MBSS support HT and atleast one HT20 peer is present. no-protection mode - is selected otherwise. This is a limited implementation of 9.23.3.5, which only considers mesh peers when determining the HT protection mode. Station's channel_type needs to be maintained.

Fix this by checking for AP VLANs as well. Also exclude 4-addr VLAN stations from num_mcast_sta - remote 4-addr stations ignore 3-address multicast frames anyway. In a typical bridge configuration they receive the same packets as 4-address unicast. This patch also fixes clearing the sdata->u.vlan.sta pointer when the STA is removed from a 4-addr VLAN.

| | | | | | | | | | | | | | | | | | | | | | | | | | The broken check leads to rate control attempting to use HT40 while the driver is configured for HT20. This leads to interesting hardware issues. HT40 can only be used if the channel type is either HT40- or HT40+ and if the channel type of the cell matches the local type.

| * mac80211: fix truncated packets in cooked monitor rxFelix Fietkau2012-04-171-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | Cooked monitor rx was recently changed to use ieee80211_add_rx_radiotap_header instead of generating only limited radiotap information. ieee80211_add_rx_radiotap_header assumes that FCS info is still present if the hardware supports receiving it, however when cooked monitor rx packets are processed, FCS info has already been stripped. Fix this by adding an extra flag indicating FCS presence. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | When testing mesh synchronization we observed a global TSF slowdown that was dependent on the number of synchronized mesh stations. This seems to be caused by the TSF adjustment (read/write) latency. Adding a small margin to the Toffset setpoint solved the problem.

| | | | | | | | | | | | | | | | | | | | | | Commit 3a25a8c8 (mac80211: add improved HW queue control) introduced a bug when running in AP mode without the IEEE80211_HW_QUEUE_CONTROL flag set. The ieee80211_check_queues() function always returns -EINVAL, preventing AP mode from starting. To fix this, check whether this flag is set before checking if cab_queue is set properly.
