Sent: 04 February 2020 05:55 I'm working on enhancing a driver for a Network Controller that supports "Checksum Offloads".

Is it one of the really broken ones that also requires the tx and rx buffers be 4 byte aligned? Get a different Network Controller, the one you have isn't 'fit for purpose' :-) David - Registered Address Lakeside, Bramley Road, Mount Farm, Milton Keynes, MK1 1PT, UK Registration No: 1397386 (Wales)
