Hi Dave,

This patchset adds two parameters to the pktgen scripts.
* The first patch adds a parameter to control the number of
  packets sent by every pktgen thread.
* The second patch adds a parameter to control the index of
  first thread, instead of always starting from cpu 0.

Series generated against net-next commit:
f7aec129a356 rxrpc: Cache the congestion window setting

Thanks,
Tariq.

V2:
* rebased to latest net-next.
* per Jesper's comments on Patch 2, fixed $F_THREAD description
  and $L_THREAD evaluation.

Tariq Toukan (2):
  pktgen: Specify num packets per thread
  pktgen: Specify the index of first thread

Use -n <num>, to specify the number of packets every
thread sends.
Zero means indefinitely.

Use "-f <num>", to specify the index of the first
sender thread.
In default first thread is #0.
