RTL8188CUS/RTL8192CU(gen1) don't support rate adaptive report hence no real txrate info can be retrieved. The vendor driver reports the highest rate in HT capabilities from the IEs to avoid empty txrate. This commit initiates the txrate information with the highest supported rate negotiated with AP. The gen2 chip keeps update the txrate from the rate adaptive reports, and gen1 chips at least have non-NULL txrate after associated. Signed-off-by:

To move the list iterator variable into the list_for_each_entry_*() macro in the future it should be avoided to use the list iterator variable after the loop body. To *never* use the list iterator variable after the loop it was concluded to use a separate iterator variable instead of a found boolean [1]. This removes the need to use a found variable and simply checking if the variable was set, can determine if the break/goto was hit.

Keeping the power to the SDIO card during system wide suspend, consumes energy. Especially on battery driven embedded systems, this can be a problem. Therefore, let's change the behaviour into allowing the SDIO card to be powered off, unless WOWL is supported and enabled. Note that, the downside from this change, is that during system resume the SDIO card needs to be re-initialized and the FW must be re-programmed. Even if this may take some time to complete, it should we worth it, rather than draining the battery. Signed-off-by:

cfg80211_ch_switch_notify uses ASSERT_WDEV_LOCK to assert that net_device->ieee80211_ptr->mtx (which is the same as priv->wdev.mtx) is held during the function's execution. mwifiex_dfs_chan_sw_work_queue is one of its callers, which does not hold that lock, therefore violating the assertion. Add a lock around the call. Disclaimer: I am currently working on a static analyser to detect missing locks. This was a reported case. I manually verified the report by looking at the code, so that I do not send wrong information or patches. After concluding that this seems to be a true positive, I created this patch. However, as I do not in fact have this particular hardware, I was unable to test it. Reviewed-by:

Add a dummy function for packet offload to eliminate warning message "c2h class 1 func 2 not support". This c2h is for debug purpose and its presence itself can do the work, so further parsing won't be required for now. Signed-off-by:

The smatch reports: rtw8852a.c:1857 rtw8852a_btc_set_wl_txpwr_ctrl() error: uninitialized symbol '_cur'. rtw8852a.c:1858 rtw8852a_btc_set_wl_txpwr_ctrl() error: uninitialized symbol '_cur'. This is because rtw89_mac_txpwr_read32() can possibly return before setting argument _cur, and the caller will use the uninitialized value. To fix this problem, check the return value of rtw89_mac_txpwr_read32(). Signed-off-by:

The newer chip will generate security header itself, so don't set IEEE80211_KEY_FLAG_GENERATE_IV in this kind of chip. But, it needs to fill key_index, PN and 802.11 header length to TX descriptor, and then hardware uses these to generate security header. Signed-off-by:

The txaddr_info is used to fill the DMA address of skb->data. The v1 version can support up to 10 entries, but the maximum size of each entry is 2047, so it fill more than one entry for large packet, like 3000 bytes. Signed-off-by:
