Hi,
Sorry if this a dumb question. Currently I'm programming a driver for the devices with variable network header len. From the Linux net stack perspective what should I do: set netdev->hard_header_len to maximum possible header and use less space that specified there or set netdev->needed_headroom to that value?
If that metters, I'll be implementing my own set of header_ops in any case.
Thank you
-- With best wishes Dmitry
