app/testpmd: fix crash when attaching a device
Checks
Commit Message
Below commit checks global device information to determine if a port uses
the softnic driver once initialized. Problem is that this information is
not available at this point when a port is initialized interactively
through a "port attach XXX" command, crashing testpmd.
This patch systematically initializes global device information to address
this issue.
Fixes: 5b590fbe09b6 ("app/testpmd: add traffic management forwarding mode")
