Description of problem:

第三方驱动mlnx-ofa_kernel-5.8-OFED.5.8.1.1.2.1.src.rpm和ice-1.8.9.tar.gz编译生成的驱动mlx5_core.ko和ice.ko同一时间只能加载一个。
比如加载mlx5_core.ko之后再加载ice.ko，将会报如下错误：
[ 1032.695185] ice: disagrees about version of symbol auxiliary_device_init
[ 1032.695188] ice: Unknown symbol auxiliary_device_init (err -22)
[ 1032.695462] ice: disagrees about version of symbol __auxiliary_device_add
[ 1032.695462] ice: Unknown symbol __auxiliary_device_add (err -22)
原因为这两个驱动都带了auxiliary驱动但互不兼容导致。
合入upstream 7de3697e9cbd4bd3d62bafa249d57990e1b8f294可以解决
