When use adapter Query method, MaxInlineDataSize we get is 444 bytes, but when CreateQueuePair pass in parameter >220, CreateQueuePair failed with ND_INSUFFICIENT_RESOURCES, why cannot use queried max inline size?

inline size is fixed 220byte.

But why the query result about adapter’s MaxInlineDataSize is 444? Is it total inline size for two different connection ports?
