Daniel, could you ping me again when this goes into the mainline kernel?

Sure, will do. It's sitting in net-next and will be pulled in with the
upcoming merge window in ~ 1 week or so.

I can ping you again for the PACKET_QDISC_BYPASS sockopt.

Thanks,

Daniel

Daniel,

I've applied this patch. I have a question below.

This last sentence is a little unclear. Would it be better as:

This can be bypassed by setting this integer
option to one; this is useful for usage scenarios similar to pktgen.

Or something like that. Also, can you elaborate a little on what 
pktgen is please.

Thanks,

Michael
