For now only tx/rx packets/bytes are reported. This is not compliant
with the PSP Architecture Specification.

Provide a PSP implementation for netdevsim.
Use psp_dev_encapsulate() and psp_dev_rcv() to do actual encapsulation
and decapsulation on skbs, but perform no encryption or decryption. In
order to make encryption with a bad key result in a drop on the peer's
rx side, we stash our psd's generation number in the first byte of each
key before handing to the peer.
