Subject: app/pdump: check for ports
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=4dbfce05836b77d53f9045933cf1003b41f9562d;p=dpdk.git

app/pdump: check for ports

In case of application build with shared library mode unless
option '-d' is passed, poll mode driver for devices is not
initialized. Notifying the user just after rte_eal_init is
pro active way of intimating the user.
