IMX6 Laird Support

[MichaelBMiner]

I have been following this guide to add meta-summit-laird to my image. I am using Hardknott 3.3 and the meta-summit-laird-pre-3.4 layer. Today I finally got the radio to be recognized by the kernel and show up in ifconfig.

Now I am trying to connect to a network but I do not have wpa_supplicant or nmcli. This is a point of frustration to me. 

In local.conf I have 

PREFERRED_RPROVIDER_wpa-supplicant = "summit-supplicant-lwb"
PREFERRED_RPROVIDER_wpa-supplicant-cli = "summit-supplicant-lwb"
PREFERRED_RPROVIDER_wpa-supplicant-passphrase = "summit-supplicant-lwb"
   
BBMASK += " \
    meta-summit-radio/meta-summit-radio-pre-3.4/recipes-packages/openssl \
    meta-summit-radio/meta-summit-radio-pre-3.4/recipes-packages/.*/.*openssl10.* \
    "
   
PREFERRED_RPROVIDER_wireless-regdb-static = "reg-lwb5-plus"
LWB_REGDOMAIN = "US"

In my image file I have

# Install necessary libraries
IMAGE_INSTALL_append = " packagegroup-core-ssh-openssh \
    openssl \
    can-utils \
    libsocketcan \
    sudo \
    boost \
    lumissil-kernel-module \
    lumissil \

IMAGE_INSTALL_append = " \
    kernel-module-lwb5p-backports-summit \
    lwb5plus-sdio-sa-firmware \
    summit-supplicant-lwb \
    summit-networkmanager-lwb \
    "

When I program my board or look at the files-in-image.txt I can see -rwxr-xr-x root root 84488 ./usr/sbin/wpa_cli is installed but no other networking tools. 

I know that the laird recipes remove and provide their own version of wpa_supplicant but they appear to be missing. 

For more information I am using laird version lrd-11.39.0.x
