What’s new in 7.1beta3 (2020-Dec-02 15:59):
!) added support for “Cake” and “FQ_Codel” type queues;
!) added new experimental wireless package “wifiwave2” for ARM devices with more than 256 MB of RAM (CLI only);
*) bgp – template parameters are now exposed in connection;
*) chr – added support for SR-IOV
*) routing – added “route”, “routing table”, “route rules” and BGP configuration migration from RouterOS v6 after upgrade;
*) routing – renamed “instance” menu to “id”;
*) other fixes and improvements;

仅支持内存大于256MB的ARM设备,当前仅支持命令行操作。wifiWave2我查了下,更完美的支持802.11ac,802.11ac标准最关键的四种技能:256QAM调制模式、80/160MHz频宽、更高空间流和MU-MIMO技术,Wave2对以上四种技能都支持。
wifiwave2功能包需要单独安装,当前仅兼容IPQ4019和QCA9984的无线接口,仅支持ARM构架的设备,要求10MB存储空间和至少256MB内存,当前7.1beta3兼容以下四种设备:
hAP ac³ (non-LTE)
Audience*
Audience LTE6 kit*
RB4011iGS+5HacQ2HnD**
* 请注意wifiwave2功能包不兼容CAPsMAN.
** 注意在RB4011iGS+5HacQ2HnD上的2.4GHz无线接口无法兼容wifiwave2功能包,它不能与已安装的包一起使用。
升级到v7.1beta3后发现CRS3系列的l3hw配置有改变,fw的nat转发参数已经没有了,只保留了no和yes选项
看来nat硬件转发还存在问题
发现7.1beta3在CRS317创建src-nat,action=masquerade规则后,再删除该规则,CPU达到40%,且删除动作持续了3-4秒钟
