On 16.04 there are lots of warnings for paths generated under /proc/sys/net/ipv6/conf/ of the form:
NetworkManager[2043]: <error> [1516281647.5546] Failed asserting path component: "hfp/org/bluez/hci0/dev_2C_8A_72_15_A8_55" NetworkManager[2043]: <warn> [1516281647.5546] IPv6 property path is too long: '/proc/sys/net/ipv6/conf/hfp/org/bluez/hci0/dev_2C_8A_72_15_A8_55/accept_ra'
These 2 messages occur for all of:
accept_ra accept_ra_defrtr accept_ra_pinfo accept_ra_rtr_pref disable_ipv6 hop_limit use_tempaddr
In this case the device is a mini-PICe GSM cellular modem - not quite sure why it is showing up with a Bluetooth path though!
