Hardware do not support "real" broadcast on the air. Use method similar to the Directed Multicast Service (DMS) as described in the 10.23.15.2 "DMS procedures" This service copies frame and delivers unicast for each associated peer Do the following: send original frame to 1-st Tx vring, and send copies to all other active vrings. As currently hardware/firmware don't support A-MSDU, convert broadcast frame to unicast instead of wrapping it in A-MSDU Signed-off-by:

When running multiple connections, hardware can't do BACK reordering and it should be done on the host. Model after mac80211's implementation. Drop RCU for now; to be re-added when BACK will be stabilized BACK handshaking is not implemented yet in the hardware, pretend it was done to support the way FW operating Signed-off-by:

Enable multiple (up to 8 - HW/FW limitation) simultaneous connections. Each connection has its own CID (connection ID) that describes chip's beam-forming entity. Tx Vring should refer to correct CID for frame to reach its destination. Signed-off-by:

Print '_' for the 'idle' descriptors - this makes vring representation more visible. Also, for the Tx side, differentiate descriptors having associated skb's - print ones with skb as 'H' and without as 'h'. Good to represent scattered frames. Signed-off-by:

The intstatus in sdio code can be updated from different threads. To protect intstatus access, atomic functions are used. The loop was replaced using atomic_set_mask(). Reviewed-by:

Some stations reset the sequence number for traffic-ids (TIDs) as they initiate a block-ACK session. In order to detect such behavior, mwifiex must note the starting sequence number given during the ADDBA request. If the first received sequence number after the ADDBA falls outside the receive window for this TID but after the the ADDBA starting sequence number, we can assume that this AP has reset its sequence number during the ADDBA. In this case we must adjust the input window backward to incorporate this received sequence number instead of ignoring it. Otherwise, we could fail to successfully retrieve an arbitrarily large number of downstream frames at the beginning of the block-ACK session. Signed-off-by:

SDIO dpc scheduling is done (repeated) when counter is set. This counter gets decreased when dpc is finished. It is more efficient to set counter to 0 before the dpc is actullay run. This will minimize the frequency with which dpc is executed. Reviewed-by:

The SDIO driver has a 16-bit field defined in the skbuff control buffer. However, it is accessed as a u32 overwriting other control info. Another issue is that the field is not initialized for networking packets, but the control buffer content is unspecified as other networking layers can use it. Reviewed-by:

Survey stats such as channel busy time, rx busy time and noise are collected when sw_scan starts for every switched new channel. This happens till sw_scan stops. All the collected stats are shared up when get_survey() is called. This implements support for ACS feature from Hostapd. Signed-off-by:

Certain HW options (TX packet retry count, CW configuration and TX power configuration) can be specified in both the TX packet descriptor and also into HW "global" registers. The HW is thus configured to honour the global register or the TX descriptor field depending by the case. This patch adds few comments that hopefully clarify in which cases the driver uses one method and in which cases it uses the other. Signed-off-by:

During driver initialization, some skbs are preallocated for RX. Currenly if the allocation fails, the driver's allocation routine exits immediatly but it will return zero (success) anyway. In this way the driver will continue initialization with buggy pointers around. This patch makes the driver's allocation routine to return an error value and to print a complaint message when skb allocation fails. In this way its caller will not go further, avoinding the driver to successfully load, and preventing dereferencing buggy pointers. An hint is thus printed about why the driver failed. Signed-off-by:

During initialization a number of RX skbs are allocated and mapped for DMA. Currently if pci_map_single() fails, it will result in passing to the HW a wrong DMA address (to write to!). This patch adds check for this condition and eventually causes the driver not to initialize, avoiding at least dangerous DMAs. Signed-off-by:
