Using a Archer C7 with the optimized snapshot on a DS--Lite line i found this in the log, one per second at day and night. The throughput is lowered to 1/3 and ping above 150ms since these errors in syslog.

So i got the idea to fire up the related script 'dslite.sh' by hand and got this.
root@scylla:/lib/netifd/proto# sh ./dslite.sh
./dslite.sh: line 102: add_protocol: not found
root@scylla:/lib/netifd/proto# opkg install ds-lite
Package ds-lite (7-2) installed in root is up to date.
As the package is installed, what produce the error here?
