基于MT7620的WIFI网关在运行过程中，可能会出现"Mgmt Ring Full"； 有时出现这些打印信息后，WIFI client无法连接上WIFI网关；
Qidx(0), not enough space in MgmtRing, MgmtRingFullCount=254!
Qidx(0), not enough space in MgmtRing,MgmtRingFullCount=255!
Qidx(0), not enough space in MgmtRing,MgmtRingFullCount=256!
Qidx(0), not enough space in MgmtRing,MgmtRingFullCount=257!
Qidx(0), not enough space in MgmtRing,MgmtRingFullCount=258!
Qidx(0), not enough space in MgmtRing,MgmtRingFullCount=259!
尝试通过分析Ralink WIFI driver源码，查找原因，，以及可能的规避办法。
