Subject: [dpdk-dev] [PATCH] lib/lib_eal:add mellanox kernel driver type
Date: Wed, 23 Aug 2017 10:48:01 +0800 [thread overview]
Message-ID: <201708230251.v7N2pSSi009414@mse01.zte.com.cn> (raw)
When use bond function in mellanox driver environment, we call the
find_port_id_by_pci_addr() function,if we don't add mellanox kernel
driver type in enum rte_kernel_driver, the function will return -1
because kdrv unknown, so we add the mellanox driver type, and when
scan the pci, fill the kdrv to fix this problem.
