can you add HUAWEI EC306 Rev. B USB Stick, to supported hardware
we a going to build large project and selecting routing platform for that 751U 2HnD. At this time i've got a problem to use this modem on mtu more than 700 byte, only with this paket leng everything works.
on 5.25 and 6.0 version I test it the same, mangle and change mss helps only to 700byte packet length.
