+into an array key and use that to key the se_tree_insert32_array and

+In order to support text string in a case insensitive way add the
+EMEM_TREE_STRING_NOCASE flag. This will uppercase all string data before using

 leave only the bits needed to make the field when ANDed with a value.
 The proto_tree routines will calculate 'bitshift' automatically
 from 'bitmask', by finding the rightmost set bit in the bitmask.
+This shift is applied before applying string mapping functions or 
+filtering.
 If the field is not a bitfield, then bitmask should be set to 0.
