[ 17/47] cdc_ether: add Novatel USB551L device IDs for FLAG_WWAN

[Greg KH <gregkh@linuxfoundation.org>]

3.3-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Williams <dcbw@redhat.com>

commit 4e6304b8420aba5311ba21fd68dab2924ae4d91a upstream.

Needs to be tagged with FLAG_WWAN, which since it has generic
descriptors, won't happen if we don't override the generic
driver info.
