New Revision: 312618
URL: https://svnweb.freebsd.org/changeset/base/312618
Log:
[athalq] fix rxtimestamp wrapping; print out per-packet timestamp deltas.
The delta here is just between the current TX/RX copmletion and the previous
TX/RX completion. The metadata needed to link TX descriptor timestamps to
their
/completion/ timestamp isn't there yet.
