You obviously mean edgerouter LITE right? there is no LTE = wireless edgerouter, though that would be nice as a backup/failover

As I pointed out here, =C2=A0there is more w= ork to be done =C2=A0on that =C2=A0front

http://community.ubnt.com/t5/EdgeMAX/= S-FQ-CoDel-Support-Possible/m-p/799394#M28651

Mostly =C2=A0my hope =C2=A0is to get a SQM-like shaper/aqm/scheduler rewrit= ten
in =C2=A0the vyatta command =C2=A0language that works at =C2=A0rates =C2=A0= up =C2=A0to 200Mbit.

All the published examples =C2=A0have problems:

http://www.five-ten-sg.com/mapper/bufferbloat =C2=A0for =C2=A0example,= =C2=A0uses SFQ
and a very small queue length that is probably ineffective.

There =C2=A0have been various other =C2=A0examples forwarded to =C2=A0me th= at all
need =C2=A0some love,
including =C2=A0one =C2=A0very elaborate one that uses ifb semi-correctly, = and
then goes nutso =C2=A0with
ack prioritization. =C2=A0(can't find any of these now)

...

And =C2=A0it did look that adding BQL support was easily possible for =C2= =A0the
underlying driver, =C2=A0but I didn't =C2=A0sink =C2=A0any time =C2=A0i= nto =C2=A0that =C2=A0- the
key "driver" (it's really an =C2=A0interface =C2=A0 to a bina= ry blob) is =C2=A0in:

drivers/net/ethernet/octeon

and =C2=A0it's =C2=A0unclear =C2=A0how much buffering is built into =C2= =A0the blob.
