My tests with newer Sierra devices and this issue (CTL vs WDA) yielded
more or less the same results. This is, wwan data format can be
changed with both ways successfully, with the difference being that
the WDA service is just much better documented. Recent libqmi/qmicli
has support for WDA, btw:
  --wda-set-data-format=[raw-ip|802-3]
  --wda-get-data-format

The problem for the reporter may just be that by default raw-ip is
configured in the WWAN interface; or if it has 2 interfaces, one may
be raw-ip and the other 802-3. qmicli doesn't change the data format
by default (as ModemManager does), so the issue may just be that 802-3
needs to be explicitly requested via qmicli...

Gopakumar, can you try to run:
 $ qmicli --wds-noop --device-open-net="net-802-3|net-no-qos-header"
and then your normal WDS connection setup?

Or, with a newer libqmi:
$ qmicli --wda-set-data-format="802-3"
