From: Miaohe Lin <linmiaohe@huawei.com> EulerOS inclusion category: performance bugzilla: https://gitee.com/openeuler/kernel/issues/ICMI9V -------------------------------- Ipvlan l2e mode will cache skbuff for local xmit in ipvlan_xmit_mode_l2e. But when tso/gso is disabled, this would result in performance loss. So we should stop caching the skbuff when tso/gso is disabled.
