    I can't say much about the firmware [1] inclusion or the procedure of
    it into linux-firmware [2].
    Maybe, Ben can explain the procedure and what has to be considered
    before inclusion in linux-firmware.
    The original firmware and helper images were extracted from a Netgear
    Windows driver [1].

    From what I read in the OpenWrt forum posting [3]: You wanted to care
    for inclusion:

    "Firmware isn't included in the kernel tree anymore, there's the
    linux-firmware git tree for that these days. I will contact some
    people at Marvell to ask whether 8361P firmware can be included
    there."

    Some more concerns...
    Dunno, if [4] is really correct and how to use one and same device-id
    for 8363 ***and*** 8361P:
    ...
    { PCI_VDEVICE(MARVELL, 0x2a02), .driver_data = MWL8363, },
    ...
    Curious about a statement from hauke...

    Adding the device-id in case of 8361P is not enough (see attached patch)

    I am looking forward to having support for 8361P soon.

    P.S.: I have re-added Readme and patch as there are new CCs.

    mkdir mwl8k
    cd mwl8k

    ### Download c-file (extract firmware) and Windows setup file (incl. firmware)

    mkdir files
    cd files
    wget -O mrv8k_extract_fw.c 'http://marc.info/?l=linux-wireless&m=126540674419330&q=p3'

    ### Extract firmware blob

    mkdir .tmp ../firmware
    cabextract -F Disk1/data*.* -d .tmp wn311t_4_2_setup.exe
    unshield -g Driver -d .tmp x .tmp/Disk1/data1.cab

    ./mrv8k_extract_fw .tmp/Driver/netmw145.sys
    mv *.fw ../firmware/
    rm -r -f .tmp

    ### Check MD5SUM and rename firmware/helper image files for 8361P/8363
