They seem to be there for the raspberry pi units but not available for banana pi units.
Yeah.. this is where the Raspberry Pi community and the Rasbian distribution makes the difference between their SBC and many of the other SBCs out there. Maybe the people who maintained the repos for the Banana Pi distro will add this kernel config:
CONFIG_HAMRADIO=y CONFIG_AX25=m CONFIG_AX25_DAMA_SLAVE=y CONFIG_NETROM=m CONFIG_ROSE=m CONFIG_MKISS=m CONFIG_6PACK=m CONFIG_BPQETHER=m CONFIG_BAYCOM_SER_FDX=m CONFIG_BAYCOM_SER_HDX=m CONFIG_BAYCOM_PAR=m CONFIG_BAYCOM_EPP=m CONFIG_YAM=m CONFIG_LEGACY_PTYS=y CONFIG_LEGACY_PTY_COUNT=256
Wouldn't hurt to ask!
