From: Keefe LIU <liuqifa@huawei.com> hulk inclusion category: bugfix bugzilla: 9511, https://gitee.com/openeuler/kernel/issues/I4IHL1 CVE: NA ------------------------------------------------- In commit <7a0f243de9e2> "ipvlan: Introduce l2e mode", we introduced ipvlan_default_mode as a way to enable the ipvlan's default mode. Howerver, we didn't check the value of this module parameter. This patch first fixed out a spelling error of "mode", and then add the value check for ipvlan_default_mode.
