1、问题描述
硬件配置：泰山2280V2、1822网卡
软件OS版本：centos8.1 aarch64、内核4.18.0-147.el8.aarch64
问题描述：
泰山2280V2安装centos8.1系统，内核4.18，编译1822网卡源码时报错如下所示：
使用的网卡源码版本：
SPC102：hinic-1.8.3.3
SPC104：hinic-1.8.3.14

2、原因分析及解决方法
CentOS8.1系统，虽然内核版本是4.18，但是其中的内核接口使用新内核接口，需要修改源码进行适配。
在SPC102版本上具体的修改点为：
修改ossl_knl_linux.h文件，从1731行开始
/*****************************************************************************/
#if (KERNEL_VERSION(4, 19, 0) > LINUX_VERSION_CODE)
#else /* >= 4.19 */
#define HAVE_NDO_SELECT_QUEUE_SB_DEV
#endif
修改为：
/*****************************************************************************/
#if (KERNEL_VERSION(4, 19, 0) > LINUX_VERSION_CODE)
#if (RHEL_RELEASE_CODE && (RHEL_RELEASE_VERSION(8, 0) <= RHEL_RELEASE_CODE ))
#define HAVE_NDO_SELECT_QUEUE_SB_DEV
#endif
#else /* >= 4.19 */
#define HAVE_NDO_SELECT_QUEUE_SB_DEV
#endif /* 4.19.0 */
SPC104版本的1822网卡源码修改方法同上。
3、设置驱动开机加载
cp hinic.ko /lib/modules/`uname -r`/updates
depmod `uname -r`
