Subject: [dpdk-dev] [PATCH v3] librte_ether: use RTE_ETH_VALID_PORTID_OR_ERR_RET to check port_id
Date: Wed, 18 May 2016 21:15:11 +0200	[thread overview]
Message-ID: <1463598911-18176-1-git-send-email-mauricio.vasquezbernal@studenti.polito.it> (raw)
In-Reply-To: <1463515316-4949-1-git-send-email-mauricio.vasquezbernal@studenti.polito.it>

The RTE_ETH_VALID_PORTID_OR_ERR_RET macro is used in some places
to check if a port id is valid or not. This commit makes use of it in
some new parts of the code.

Signed-off-by: Mauricio Vasquez B <mauricio.vasquezbernal@studenti.polito.it>

v3:
 - use it also in rte_eth_add_rx_callback and rte_eth_add_tx_callback 
v2:
 - add missed case
 - change also cases in examples/ethtool/lib/rte_ethtool.c
