    in the meantime, I was able to run some first tests with the ClearFog Pro:
    1) Using a fast mSATA SSD

    2) Ethernet connection over SFP

    Connecting two ClearFog Pro over a SFP fiber link. 
    # ethtool eth1 Settings for eth1:         Supported ports: [ FIBRE ]         Supported link modes:   1000baseT/Full         Supported pause frame use: Symmetric         Supports auto-negotiation: Yes         Advertised link modes:  1000baseT/Full         Advertised pause frame use: Symmetric         Advertised auto-negotiation: Yes         Speed: 1000Mb/s         Duplex: Full         Port: FIBRE         PHYAD: 0         Transceiver: external         Auto-negotiation: on         Link detected: yes Network speed was just 1Gbit/sec, we were not able to change the settings to get up to 2.5Gbit/sec.

    Any clues how to get the maximum ethernet speed over SFP? Maybe for 2.5G there has to be some special settings, or there is something missing in the kernel drivers to support 2.5G. 
    The 2.5Gbit mode for SFP can be enabled with a patch in U-Boot. I already have prepared the patch and compiled the new u-boot, but I'm having trouble to boot the new image because u-boot has some problems. (will update this post as soon as I have a solution)
    Update2: (13.03.2016)
    We were able to successfully test the 2.5Gbit mode for SFP, using two ClearFog Pro boards connected directly with two Brocade GBIC's and a 1m optical fibre cable. Testing with `iperf3` shows us the maximum network speed which is really excellent.

    This WiFi module has just arrived, hope to get it running soon...
    Specs: AR9880, 802.11ac, 2,4/5GHz, 3*3 MIMO

    WiFi is working, I just added the correct kernel modules and recompiled and installed the new kernel 4.4.4.
    CONFIG_ATH10K=m CONFIG_ATH10K_PCI=m Additionally I had to install the correct firmware files for the Compex WLE900VX card:
    /lib/firmware/ath10k/QCA988X/hw2.0/firmware-5.bin_10. /lib/firmware/ath10k/QCA988X/hw2.0/firmware-5.bin -> firmware-5.bin_10. /lib/firmware/ath10k/QCA988X/hw2.0/board.bin
