If one enables e.g. jumbo frames without mergeable buffers, packets won't fit in 1500 byte buffers we use. Switch to big packet mode instead. TODO: make sizing more exact, possibly extend small packet mode to use larger pages. Signed-off-by: Michael S.

Support this better by adding a callback drivers can use to do some early checks. Signed-off-by: Michael S.
