From: Ivan Boule Date: Tue, 16 Apr 2013 12:42:33 +0000 (+0200) Subject: ethdev: add support for device offload capabilities X-Git-Tag: spdx-start~10939 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=7238e63bce528167a7f1241e3c3b25172e7b5ad6;p=dpdk.git ethdev: add support for device offload capabilities 1) Make device RX and TX offload capabilities to be returned in the rte_eth_dev_info data structure by the function rte_eth_dev_info_get The following initial set of RX offload capabilities are defined: - VLAN header stripping - IPv4 header checksum check - UDP checksum check - TCP checksum check - TCP large receive offload (LRO) The following initial set of TX offload capabilities are defined: - VLAN header insertion - IPv4 header checksum computation - UDP checksum computation - TCP checksum computation - SCTP checksum computation - TCP segmentation offload (Transmit Segmentation Offload) - UDP segmentation offload 2) Update the eth_dev_infos_get() function of the igb and ixgbe PMDs to return the offload capabilities which are supported by the device and that are effectively managed by the driver.
