From: Ferruh Yigit Date: Fri, 29 Jun 2018 12:41:13 +0000 (+0100) Subject: ethdev: add new offload flag to keep CRC X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=70815c9ecadd;p=dpdk.git ethdev: add new offload flag to keep CRC DEV_RX_OFFLOAD_KEEP_CRC offload flag is added. PMDs that support keeping CRC should advertise this offload capability. DEV_RX_OFFLOAD_CRC_STRIP flag will remain one more release default behavior in PMDs are to keep the CRC until this flag removed Until DEV_RX_OFFLOAD_CRC_STRIP flag is removed: - Setting both KEEP_CRC & CRC_STRIP is INVALID - Setting only CRC_STRIP PMD should strip the CRC - Setting only KEEP_CRC PMD should keep the CRC - Not setting both PMD should keep the CRC A helper function rte_eth_dev_is_keep_crc() has been added to be able to change the no flag behavior with minimal changes in PMDs. The PMDs that doesn't report the DEV_RX_OFFLOAD_KEEP_CRC offload can remove rte_eth_dev_is_keep_crc() checks next release, related code commented to help the maintenance task. And DEV_RX_OFFLOAD_CRC_STRIP has been added to virtual drivers since they don't use CRC at all, when an application requires this offload virtual PMDs should not return error.
