Subject: [RFC PATCH 00/14] wifi: rtl8xxxu: Add AP mode support for 8188f

This series intends to bring AP mode support to the rtl8xxxu driver,
more specifically for the 8188f, because this is the HW I have.
The work is based on the vendor driver as I do not have access to
datasheets.

This is an RFC, so that there can be a discussion first before
potentially implementing support for the other chips in this driver, if
required.

Also while doing some measurements with iperf3 to compare with the
vendor driver, I saw, that TCP traffic from AP to STA is slower than in
the vendor driver. For UDP it looks fine. I hope I can get some help to
fix this.

* vendor driver:

  without 802.11n:
    UDP (AP -> STA): 27 Mbits/sec
    UDP (STA -> AP): 33 Mbits/sec
    TCP (AP -> STA): 24 Mbits/sec
    TCP (STA -> AP): 26 Mbits/sec

  with 802.11n:
    UDP (AP -> STA): 51 Mbits/sec
    UDP (STA -> AP): 35 Mbits/sec
    TCP (AP -> STA): 40 Mbits/sec
    TCP (STA -> AP): 36 Mbits/sec

* rtl8xxxu:

  without 802.11n:
    UDP (AP -> STA): 25 Mbits/sec
    UDP (STA -> AP): 31 Mbits/sec
    TCP (AP -> STA):  3 Mbits/sec !
    TCP (STA -> AP): 25 Mbits/sec

  with 802.11n:
    UDP (AP -> STA): 41 Mbits/sec
    UDP (STA -> AP): 36 Mbits/sec
    TCP (AP -> STA):  3 Mbits/sec !
    TCP (STA -> AP): 32 Mbits/sec

Thanks,
  Martin
