OK, cool.  Will the big packets be non-linear skbs?

Because then it would make sense for a device with a huge MTU to want
to accept them without linearizing them, even if it had to copy them
to checksum the data.  Otherwise with fragmented memory it would be
impossible to handle such big packets at all.
