Subject: [PATCH] app/test: fix data length of each packet segment
Date: Mon, 6 Mar 2023 04:33:51 +0800 [thread overview]
Message-ID: <20230305203351.13599-1-zobin1999@gmail.com> (raw)
Assign correct data length to each segments according
to the given pkt_len and nb_pkt_segs, instead of
using pkt_len as the data_len of every packet segment
Fixes: a9c9e9698d5e ("app/test: allow to create packets of different sizes")
