MobileBroadband devices needs to implement some kind of ethernet emulation. This is necessary as ppp uses to much overhead to reach the high bandwidth HSPA devices can provide. Still HSPA modems needs a tty channel for controlling the device as this is legacy requirement defined by GSM and 3GPP specification. So the control-plane for high speed MobileBroadband devices is a tty, this is one major difference from usbX/ethX/wlanX devices. I think that a new name is good to indicate that MobileBroadband devices are diffrent in how they are setup. Also it is good to have one name that dont implies the vendor name for this type of devices. /BR Carl Nordbeck > -----Original Message----- > From: Greg KH [mailto:greg@xxxxxxxxx] > Sent: den 17 november 2008 22:31 > To: Carl Nordbeck > Cc: Oliver Neukum; Carl Nordbeck; Alan Stern; linux-net; linux-usb > Subject: Re: [PATCH]MBM: add Ericsson mbm driver > > On Mon, Nov 17, 2008 at 10:01:01PM +0100, Carl Nordbeck wrote: > > The idea is to have both a flag indicating this is of the type > > MobileBroadbandNetwork FLAG_MBN and use a new name of the > device mbX. > > This clearly indicate that this is not host-host connection nor a > > normal ethernet device. > > Then what is it? > > > But still can reuse usbnet and have compability to userspace? > > What compatibility?
