MM_BEARER_IP_FAMILY_ANY broken in MM 1.12.0?

[Amol Lad]

I'll test it straight away but before that, is similar change needed in proto_modemmanager_teardown () as well?

proto_modemmanager_teardown() {
local interface="$1"

local modemstatus bearerpath errorstring
local bearermethod_ipv4 bearermethod_ipv6

local device lowpower iptype
json_get_vars device lowpower iptype

echo "stopping network"

# load connected bearer information, just the first one should be ok
modemstatus=$(mmcli --modem="${device}" --output-keyvalue)
bearerpath=$(modemmanager_get_field "${modemstatus}" "modem.generic.bearers.value\[1\]")
[ -n "${bearerpath}" ] || {
echo "couldn't load bearer path"
return
}

# ip type IPv4 is assumed if none explicitly given
[ -z "${iptype}" ] && iptype="ipv4"

# load bearer connection methods
bearerstatus=$(mmcli --bearer "${bearerpath}" --output-keyvalue)
[ "$iptype" = "ipv4" ] || [ "$iptype" = "ipv4v6" ] && {
bearermethod_ipv4=$(modemmanager_get_field "${bearerstatus}" "bearer.ipv4-config.method")
echo "IPv4 connection teardown required in interface ${interface}: ${bearermethod_ipv4}"
}
[ "$iptype" = "ipv6" ] || [ "$iptype" = "ipv4v6" ] && {
bearermethod_ipv6=$(modemmanager_get_field "${bearerstatus}" "bearer.ipv6-config.method")
echo "IPv6 connection teardown required in interface ${interface}: ${bearermethod_ipv6}"
}
