[dpdk-dev] [PATCH v1] doc/eth: update document for functional limitation

[Vipin Varghese <vipin.varghese@intel.com>]

ETH APIs dev_attach and dev_dettach can be exercised from primary
process only. Secondary process only maps the resource and does
not have access to internal device list. Hence updating documentation
to reflect the same.
