Merge branch 'pktgen-next'

Jesper Dangaard Brouer says:

====================
The following series introduce some pktgen changes

Patch01:
 Cleanup my own work when I introduced NO_TIMESTAMP.

Patch02:
 Took over patch from Alexei, and addressed my own concerns, as Alexie
 is too busy with other work, and this will provide an easy tool for
 measuring ingress path performance, which is a hot topic ATM.

 Changes were primarily user interface related.  Introduced a separate
 "xmit_mode" setting, instead of stealing one of the dev flags like
 Alexei did.
