octeon: add support for max_rx_frame_size update
This patch adds capability to update max_rx_frame_size on octeon
port.
Initial MTU value is being set in the "oct_port_start", which is
invoked every time the Ethernet interface is brought up, thus
overwriting any MTU value set by VPP CLI.
Moved the MTU initialization to "oct_port_init" to address this.
Type: feature
