* rtlwifi: Replace old-style license informationLarry Finger2019-02-191-24/+2
| | | | | | | | The traditional license information is replaced by the SPDX form. There are no code changes. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
* rtlwifi: cleanup the code that check whether TX ring is availablePing-Ke Shih2017-12-071-1/+0
| | | | | | | | | | Remove the duplicate checking of TX ring's available number, and remove the variable to store available number that can be calculated by read/write pointers.

* rtlwifi: fix the wrong size to calculate fifo spacePing-Ke Shih2017-12-071-2/+2
| | | | | | | | | | Give correct fifo size to calculate fifo space. Fortunately, the values of RTL_PCI_MAX_RX_COUNT and TX_DESC_NUM_92E are the same in old code, so it still works.

| | | | | | | | | | | | | 8822be checks H2CQ by int_d, so we extend to four ISR. Also, irq_mask is extended to four.

The problem is due to rtl8192ce and rtl8192cu sharing routines, and having different layouts of struct rtl_pci_priv, which is used by rtl8192ce, and struct rtl_usb_priv, which is used by rtl8192cu. The problem was resolved by placing the struct bt_coexist_info at the head of each of those private areas.

The diffstat looks scary as we created a new directory realtek for all realtek drivers. In the future I'm planning to create similar directories for all vendors, currently we just have ath, mediatek and realtek. This change has been in linux-next for a couple of weeks so it should be safe, but of course you never know. There's also a new driver rtl8xxxu for few realtek USB devices. This just made it to the last linux-next build. Otherwise there's nothing really special, more info below. If time permits, and it's ok for you, I'm hoping to send you a one more pull request this week. brcmfmac * using netdev carrier state * add and rework some cfg80211 callbacks mainly for AP mode * use devcoredump when triggered by firmware event realtek * create new directory drivers/net/wireless/realtek/ for all realtek drivers, not visible to users (no kconfig changes etc) * add rtl8xxxu, a new mac80211 driver for RTL8723AU, RTL8188CU, RTL8188RU, RTL8191CU, RTL8192CU and hopefully more in the future ath10k * add board 2 API support for automatically choosing correct board file * data path optimisations * disable PCI power save for qca988x and QCA99x0 due to interop reasons wil6210 * BlockAckReq support * firmware crashdump using devcoredump * capture all frames with sniffer ==================== Signed-off-by: David S.

* rtlwifi: rtl818x: Move drivers into new realtek directoryLarry Finger2015-10-141-0/+335
Now that a new mac80211-based driver for Realtek devices has been submitted, it is time to reorganize the directories. Rather than having directories rtlwifi and rtl818x be in drivers/net/wireless/, they will now be in drivers/net/wireless/realtek/. This change simplifies the directory structure, but does not result in any configuration changes that are visable to the user.
