Larry Finger authored
All of the rtlwifi family of drivers have a similar routine that acquires the hardware info from efuse and initializes a number of variables in the driver's private area. A common routine is created for all drivers to use. Reported-by:

As interrupt is read in interrupt handler as well as interrupt processing thread, we observed a corner case issue for MSI in which interrupt gets processed twice. This patch moves interrupt reading code for MSI mode from mwifiex_interrupt_status() to mwifiex_pcie_process_int() to avoid the issue. Signed-off-by:

The PCIe driver didn't mask the host interrupts before trying to tear down. This causes lockups at reboot or rmmod when using MSI-X on 8997, since the MSI handler gets confused and locks up the system. Also tested on 8897, which does not support MSI-X (and wasn't experiencing this same bug). No regressions seen there. Signed-off-by:

PCIe-USB8997 variant is being used in the product. Let's change default firmware from PCIe-UART to PCIe-USB. So by default PCIe-USB firmware would be downloaded if version register doesn't give any information. Signed-off-by:

The two members min_scan_time and max_scan_time of structure "mwifiex_ie_types_btcoex_scan_time" are of two bytes each. The values are assigned directtly from firmware without endian conversion handling. So, wrong datas will get saved in big-endian systems. This patch converts the values into cpu's byte order before assigning them into the local members. Signed-off-by:

New firmwares (e.g. 10.10.69.36 for BCM4366) support "interface_remove" for removing interfaces. Try to use this method on cfg80211 request. In case of older firmwares (e.g. 7.35.177.56 for BCM43602 as I tested) this will just result in firmware rejecting command and this won't change any behavior. Signed-off-by:

So far when receiving event about in-firmware-interface removal our event worker was notifying listener and afterwards it was removing Linux interface. First of all it was resulting in slightly unexpected order. The listener (del_virtual_intf callback) was (usually) returning with success before we even called unregister_netdev(ice). Please note this couldn't be simply fixed by changing order of calls in brcmf_fweh_handle_if_event as unregistering interface earlier could free struct brcmf_if. Another problem of current implementation are possible lockups. Focus on the time slot between calling event handler and removing Linux interface. During that time original caller may leave (unlocking rtnl semaphore) *and* another call to the same code may be done (locking it again). If that happens our event handler will stuck at removing Linux interface, it won't handle another event and will block process holding rtnl lock. This can be simply solved by unregistering interface in a proper callback, right after receiving confirmation event from firmware. This only required modifying worker to don't unregister on its own if there is someone waiting for the event. Signed-off-by:

scan_block flag is used to block scan operation when 4 way handshake is in progress. Sometimes it doesn't get cleared due to incomplete association. An example is assoc request/response is done, but add key operation get canceled in some corner cases. As a result, further association/scan operations are blocked. This patch fixes the problem by clearing scan_block flag. Signed-off-by:

This allows the user to specify DMA aggregation timout and block count. Blocks are presumably always 512 bytes, so the minimum block count is 6 for 802.11 packets. Signed-off-by:

gen2 chips as well as 8188eu seems to use this register for setting DMA timeout threshold values, however the 8192cu is using REG_USB_DMA_AGG_TO. Set both to be on the safe side. Signed-off-by:

This enables aggregation on rtl8192cu and derivative parts. This uses the same parameters as for rtl8723au. Signed-off-by:

Jes Sorensen authored
Implement rtl8xxxu_gen1_init_aggregation(). Aggregation should be the same for all gen1 parts. We may want to allow for tuning parameters in the fileopes struct. For now this is based allocating 16KB RX buffers, leaving 16000 bytes for actual packets, and the rest for the skb overhead. Signed-off-by:

Jes Sorensen authored
The old allocation didn't leave space for phystats in the buffer, allowing the packet to be rejected if a frame size of size IEEE80211_MAX_FRAME_LEN was received. Signed-off-by:

This implements support for demuxing aggregated RX packets on gen1 devices, using the rxdesc16 format. So far this has only been tested with rtl8723au devices. Signed-off-by:
-
Jes Sorensen authored
This corrects the definition of rxdesc16 to correctly specify pkt_cnt for aggregated packets. This is based on the code of the vendor rtl8723au driver, as opposed to the struct definitions they use. Signed-off-by:

Jes Sorensen authored
When handling aggregated packets, we'll get a new ieee80211_rx_status for each cloned skb, so passing in the pointer from the outside doesn't make sense. Signed-off-by:

This patch fixes below NULL pointer dereference observed in suspend stress test. When scan is cancelled during system suspend, we may end up aceesing "priv->scan_request" in corner case.
