When DRIVER_REQUIRE_TXSTATUS_FIFO is set, intialize the txstatus_fifo, but initialize rt2x00dev->txstatus_tasklet only when both DRIVER_REQUIRE_TXSTATUS_FIFO and rt2x00dev->ops->lib->txstatus_tasklet are set. This allows the txstatus_fifo to be used by rt2800usb which does not use txstatus_tasklet.

This patch revamps some common code-paths which are shared between (re-)initialization and suspend/resume subroutines. It also adds some helpful comments about quirks and associated difficulties. It's quite big, but it should fix #25382: <https://bugzilla.kernel.org/show_bug.cgi?id=25382> And hopefully the code is robust enough to deal with all possible suspend/resume scenarios without requiring the user to do any sort of manual and possibly dangerous work.

By removing two "safety" msleeps (and an echo nop), the channel change delay is effectively halved. Previously, the delay could be as long as 260 ms and the device could not go off-channel without risking to miss the next DTIM beacon [interval ~307 ms].

ath5k_reset is called from process context and takes the cc_lock with plain spin_lock(), but cc_lock can also be taken from tasklets in softirq context. Thus we need to at least use spin_lock_bh.

Looks that we do not set correctly antennas when scanning on 5Ghz band and when bluetooth is enabled, because priv->cfg->scan_tx_antennas[band] is only defined for IEEE80211_BAND_2GHZ.

由 Johan Hedberg 提交于
The initialization function used by hci_open_dev (hci_init_req) sends many different HCI commands. The __hci_request function should only return when all of these commands have completed (or a timeout occurs). Several of these commands cause hci_req_complete to be called which causes __hci_request to return prematurely. This patch fixes the issue by adding a new hdev->req_last_cmd variable which is set during the initialization procedure. The hci_req_complete function will no longer mark the request as complete until the command matching hdev->req_last_cmd completes.

It looks like some hardware registers are left into undefined state after suspend/resume. At minimum, this can cause odd issues related to key cache and hardware trying to encrypt/decrypt frames unexpectedly. This seems to happen even when there is no keys configured, i.e., hardware can end up touching TX frames just based of invalid key cache context even if the driver is not asking a specific entry to be used. In addition, RX can likely be affected. This patch fixes this issue.

Sometimes device returns wrong number of items in bssid-list. Appears that some specific beacons trigger this problem and leads to very poor scanning results. Workaround by ignoring num_items received from device and walkthrough full bssid-list buffer. v2: Fix buffer range checks and reading next item length. Old code read behind buffer on last item but didn't use those values as 'count' would also reach zero. Also fix resizing of buffer if device has larger buffer, old code assumed that BSSID-list OID would return same buffer size when it really can return yet another new larger length.
