Subject: [dpdk-dev] [PATCH 21/22] config: add configurations for enabling 'Extended Tag' or resetting 'Max Read Request Size'
Date: Wed, 21 May 2014 23:30:20 +0800 [thread overview]
Message-ID: <1400686221-4696-22-git-send-email-helin.zhang@intel.com> (raw)
In-Reply-To: <1400686221-4696-1-git-send-email-helin.zhang@intel.com>
Sys files of 'extended_tag' and 'max_read_request_size' have been
supported in igb_uio, and can be changed during probing PCI. Three
items in configuration files are needed to support them at compile
time. Those three items are,
- CONFIG_RTE_PCI_CONFIG
- CONFIG_RTE_PCI_EXTENDED_TAG
- CONFIG_RTE_PCI_MAX_READ_REQUEST_SIZE
