[PATCH] net/ixgbe: support detection of hot swapped SFP/SFP+

[Srini J <srinidpdk@gmail.com>]

From: Srinivasan Jayarajan <srinidpdk@gmail.com>

    Adds support to use a different SFP/SFP+ without restarting the
    DPDK app. rte_eth_dev_stop()/rte_eth_dev_start() will need
    to be called on the port to detect the SFP/SFP+ change.
