mac80211: split ath patch in dedicated subdir

The ath patch number is already large and adding other patch for ath11k
will add more confusion with the patch numbering.
Since the support of ath11k based device is imminent, prepare the mac80211
ath patch dir and split it in the dedicated ath5k, ath9k, ath10k and ath11k
(empty for now).

+Subject: [PATCH] ath10k: add CCMP PN replay protection for fragmented
+ frames for PCIe
+
+PN replay check for not fragmented frames is finished in the firmware,
+but this was not done for fragmented frames when ath10k is used with
+QCA6174/QCA6377 PCIe. mac80211 has the function
+ieee80211_rx_h_defragment() for PN replay check for fragmented frames,
+but this does not get checked with QCA6174 due to the
+ieee80211_has_protected() condition not matching the cleared Protected
+bit case.
+
+Validate the PN of received fragmented frames within ath10k when CCMP is
+used and drop the fragment if the PN is not correct (incremented by
+exactly one from the previous fragment). This applies only for
+QCA6174/QCA6377 PCIe.

+Subject: [PATCH] ath10k: Fix TKIP Michael MIC verification for PCIe
+
+TKIP Michael MIC was not verified properly for PCIe cases since the
+validation steps in ieee80211_rx_h_michael_mic_verify() in mac80211 did
+not get fully executed due to unexpected flag values in
+ieee80211_rx_status.
+
+Fix this by setting the flags property to meet mac80211 expectations for
+performing Michael MIC validation there. This fixes CVE-2020-26141. It
+does the same as ath10k_htt_rx_proc_rx_ind_hl() for SDIO which passed
+MIC verification case. This applies only to QCA6174/QCA9377 PCIe.

+Subject: [PATCH] ath10k: Validate first subframe of A-MSDU before
+ processing the list
+
+In certain scenarios a normal MSDU can be received as an A-MSDU when
+the A-MSDU present bit of a QoS header gets flipped during reception.
+Since this bit is unauthenticated, the hardware crypto engine can pass
+the frame to the driver without any error indication.
+
+This could result in processing unintended subframes collected in the
+A-MSDU list. Hence, validate A-MSDU list by checking if the first frame
+has a valid subframe header.
+
+Comparing the non-aggregated MSDU and an A-MSDU, the fields of the first
+subframe DA matches the LLC/SNAP header fields of a normal MSDU.
+In order to avoid processing such frames, add a validation to
+filter such A-MSDU frames where the first subframe header DA matches
+with the LLC/SNAP header pattern.
+
+Tested-on: QCA9984 hw1.0 PCI 10.4-3.10-00047

+Subject: ath10k: increase rx buffer size to 2048
+
+Before, only frames with a maximum size of 1528 bytes could be
+transmitted between two 802.11s nodes.
+
+For batman-adv for instance, which adds its own header to each frame,
+we typically need an MTU of at least 1532 bytes to be able to transmit
+without fragmentation.
+
+This patch now increases the maxmimum frame size from 1528 to 1656
+bytes.
+
+Tested with two ath10k devices in 802.11s mode, as well as with
+batman-adv on top of 802.11s with forwarding disabled.
+
+Fix originally found and developed by Ben Greear.

+Adds LED and GPIO Control support for 988x, 9887, 9888, 99x0, 9984 based
+chipsets with on chipset connected led's using WMI Firmware API.  The LED
+device will get available named as "ath10k-phyX" at sysfs and can be controlled
+with various triggers.  adds also debugfs interface for gpio control.
+
+This patch is specific for OpenWRt base, as is use old backported package
+with old wireless source. Support for QCA9984 is removed and a simbol
+is added to local-simbol file to export the actually compile the code 
+with the ATH10K_LEDS simbol.

+Subject: ath10k: fix max antenna gain unit
+
+Most of the txpower for the ath10k firmware is stored as twicepower (0.5 dB
+steps). This isn't the case for max_antenna_gain - which is still expected
+by the firmware as dB.
+
+The firmware is converting it from dB to the internal (twicepower)
+representation when it calculates the limits of a channel. This can be seen
+in tpc_stats when configuring "12" as max_antenna_gain. Instead of the
+expected 12 (6 dB), the tpc_stats shows 24 (12 dB).
+
+Tested on QCA9888 and IPQ4019 with firmware 10.4-3.5.3-00057.

+Subject: ath10k: adjust tx power reduction for US regulatory domain
+
+FCC allows maximum antenna gain of 6 dBi. 15.247(b)(4):
+
+> (4) The conducted output power limit
+> specified in paragraph (b) of this section
+> is based on the use of antennas
+> with directional gains that do not exceed
+> 6 dBi. Except as shown in paragraph
+> (c) of this section, if transmitting
+> antennas of directional gain greater
+> than 6 dBi are used, the conducted
+> output power from the intentional radiator
+> shall be reduced below the stated
+> values in paragraphs (b)(1), (b)(2),
+> and (b)(3) of this section, as appropriate,
+> by the amount in dB that the
+> directional gain of the antenna exceeds
+> 6 dBi.
