Subject: always initalize the size of a packet (forgotten on checkpoints
X-Git-Tag: m5_1.0_tutorial~76^2~24^2~8
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=86836124ed272945e9d360c068728cd03917398d;p=gem5.git

always initalize the size of a packet (forgotten on checkpoints
in some places).  use the constructor for setting the size.
