From e0e16672ee9e2c31d9601d762cf934196b13a7fc Mon Sep 17 00:00:00 2001 From: Tariq Toukan Date: Thu, 15 Jun 2017 19:07:22 +0300 Subject: [PATCH] pktgen: Specify the index of first thread Use "-f ", to specify the index of the first sender thread. In default first thread is #0. Signed-off-by: Tariq Toukan Cc: Jesper Dangaard Brouer Acked-by: Jesper Dangaard Brouer Signed-off-by: David S.
