octeontx2-pf: Clear RSS enable flag on interace down
[ Upstream commitf12098ce9b
] RSS configuration can not be get/set when interface is in down state as they required mbox communication. RSS enable flag status is used for set/get configuration. Current code do not clear the RSS enable flag on interface down which lead to mbox error while trying to set/get RSS configuration. Fixes:85069e95e5
