  - ice防止在重新加载期间发生空指针取消引用在重新加载期间调用 ethtool 可导致调用跟踪因为一段时间未配置 VSI但 netdev 还存在。若要修复此问题请为 VSI 的取消配置和配置添加 rtnl 锁定。释放后将 ::num_q_vectors 设置为 0并在与 ring 相关的 ethtool 操作中添加 ::tx/rx_rings 检查。在 ice_start_eth() 中添加正确的过滤器展开。复制 $watch -n 0.1 -d 'ethtool -g enp24s0f0np0' $devlink dev reload pci/0000:18:00.0 action driver_reinit 调用跟踪修复后
