Subject: [dpdk-dev] [PATCH v6 1/2] librte_ether: modify internal callback function
Date: Thu, 6 Oct 2016 17:48:09 +0100 [thread overview]
Message-ID: <1475772490-10491-2-git-send-email-bernard.iremonger@intel.com> (raw)
In-Reply-To: <1475753191-17391-1-git-send-email-bernard.iremonger@intel.com>
add cb_arg parameter to the _rte_eth_dev_callback_process function.
Adding a parameter to this function allows passing information
to the application when an eth device event occurs such as
a VF to PF message.
This allows the application to decide if a particular function
is permitted.
drivers/net: add parameter to callback process function
add parameter to call of _rte_eth_dev_callback_process function
in the following PMD's:
net/bonding
net/e1000
net/i40e
net/mlx4
net/mlx5
net/nfp
net/thunderx
net/vhost
net/virtio
net/enic
app/test: add parameter to callback process function
add parameter to call of _rte_eth_dev_callback_process function
