Under Windows, with Intel NIC the Jumbo size that is available is 4096 and 9016, there isn't a way to set it to 9000, which is the maximum QNX allows. Given that this is the exact same hardware on QNX and Windows, that e1000 is derived from Intel driver ( I was told ) how come the maximum under QNX is 9000? Or anyone know a way to get Intel driver under Windows to use jumbo frame of 9000 bytes
This must be something to do with the stack, as the driver can handle larger mtu sizes.

It's 9000 not including the ethernet header + crc. Add those and you get 9018. Does windows include those? -seanb -----Original Message----- From: Hugh Brown [mailto:community-noreply@qnx.com] Sent: Thu 2/17/2011 11:09 AM To: general-networking Subject: Re: MTU Size This must be something to do with the stack, as the driver can handle larger mtu sizes.

All I know is that there is only 3 settings default/4096/9016 (not sure about the 4096, don't have access to that PC at the moment). Our switch support 16K frame though, which are neither available in QNX and Windows. > -seanb > > -----Original Message----- > From: Hugh Brown [mailto:community-noreply@qnx.com] > Sent: Thu 2/17/2011 11:09 AM > To: general-networking > Subject: Re: MTU Size > > This must be something to do with the stack, as the driver can handle larger > mtu sizes. > > > On 11-02-17 9:50 AM, "Mario Charest" <community-noreply@qnx.com> > wrote: > > > Under Windows, with Intel NIC the Jumbo size that is available is 4096 > > and 9016, there isn't a way to set it to 9000, which is the maximum QNX > allows. > > > > Given that this is the exact same hardware on QNX and Windows, that > > e1000 is derived from Intel driver ( I was told ) how come the maximum > > under QNX is 9000? > > > > Or anyone know a way to get Intel driver under Windows to use jumbo > > frame of > > 9000 bytes > > > > > > > > _______________________________________________ > > > > General > > http://community.qnx.com/sf/go/post83269 > > > > > > -- > Hugh Brown (613) 591-0931 ext. 2209 (voice) > QNX Software Systems Ltd.
