What's new in 7.1beta1 (2020-Jul-21 08:58): !) added FastTrack and NAT hardware offloading support for CRS317-1G-16S+RM; !) ported features and fixes introduced in v6.47.1; *) route - added rpki-check; *) route - bgp improvements; *) route - do not allow modifying/deleting "main" table; *) route - fixed incorrectly interpreted prefix states received from RTR; *) route - fixed IPv6 ECMP connected routes; *) route - fixed IPv6 policy routing; *) route - routing rules improvements; *) wireless - fixed wireless performance for 802.11b/g/n and 802.11a/n interfaces on non-ARM architecture devices; *) other minor fixes and improvements; 我最关注的就是added FastTrack and NAT hardware offloading support for CRS317-1G-16S+RM; 现在CRS317-1G-16S+RM，支持NAT hardware offloadming，也就是nat转发下放给芯片处理，硬件转发，现在暂时没有找到官方的相关资料，如果有了，后续会做更新 7月22日；CRS317最多支持4096条NAT会话的HW处理，和多少条nat规则无关。
