上次调整了Openwrt的日志后，断流是好了不少，但是偶尔还是会发现网络开小差，继续看日志
发现内核日志里如下一些奇怪的记录
[ 2047.238147] Qidx(0), not enough space in MgmtRing, MgmtRingFullCount=331!
[ 2047.238151] Qidx(0), not enough space in MgmtRing, MgmtRingFullCount=332!
[ 2047.251358] Qidx(0), not enough space in MgmtRing, MgmtRingFullCount=333!
[ 2047.251365] Qidx(0), not enough space in MgmtRing, MgmtRingFullCount=334!
[ 2047.251369] Qidx(0), not enough space in MgmtRing, MgmtRingFullCount=335!
[ 2047.264018] Qidx(0), not enough space in MgmtRing, MgmtRingFullCount=336!
[ 2047.264025] Qidx(0), not enough space in MgmtRing, MgmtRingFullCount=337!网上查了半天，应该是那个多拨功能的记录，但是根本我也没启用多拨，原来尝试着启用，但是发现也没效果，那干脆卸载算了
于是进入软件管理，查找“mwan3”，直接移除，重启，发现多拨和负载均衡都没了，关键是可用内存从41直接跳到了62，而且用了一段时间，似乎都不在碰到假死了，大家可以一试
