As Yongseok mentioned 'show port cap all' prints the offload capabilities in a
more user friendly way  . This patch adds a summary config log after
"start" command, I think it is good to keep it brief.
Related to the "pmd.net.*.offload_flags" suggestion, we are currently using log
types to select components, it can be interesting to use feature based log
types, ethdev may register them and PMDs can use it.
************ Port 0 supported offload features: ************
VLAN stripped: off
Double VLANs stripped: off
RX IPv4 checksum: off
RX UDP checksum: off
RX TCP checksum: off
RX Outer IPv4 checksum: off
VLAN insert: off
Double VLANs insert: off
TX IPv4 checksum: off
TX UDP checksum: off
TX TCP checksum: off
TX SCTP checksum: off
TX Outer IPv4 checksum: off
TX TCP segmentation: off
TSO for VXLAN tunnel packet: off
TSO for GRE tunnel packet: off
TSO for IPIP tunnel packet: off
TSO for GENEVE tunnel packet: off
This command needs a volunteer to add missing offloading types.
