Subject: [dpdk-dev] [PATCH 2/5] ethdev: add new ops of 'check_command_supported' and 'rx_classification_filter_ctl'
Date: Thu, 24 Jul 2014 14:42:26 +0800 [thread overview]
Message-ID: <1406184149-11531-3-git-send-email-helin.zhang@intel.com> (raw)
In-Reply-To: <1406184149-11531-1-git-send-email-helin.zhang@intel.com>
Two ops of 'check_command_supported' and 'rx_classification_filter_ctl'
are added.
* 'check_command_supported' is for capability discovery. In anothoer
word, it is to check if specific feature/command is supported by
the specific port.
* 'rx_classification_filter_ctl' is for receive classifcation filter
configuring. e.g. hash function configuration, flow director
configuration. It is a common API where a lot of commands can
be implemented for different sub features.
