Sander Vanheule 0b35a08a05 realtek: correct egress frame priority assignment ... Priority values passed to the egress (TX) frame header initialiser are invalid when smaller than 0, and should not be assigned to the frame. Queue assignment is then left to the switch core logic. Current code for RTL83xx forces the passed priority value to be positive, by always masking it to the lower bits, resulting in the priority always being set and enabled. RTL93xx code doesn't even check the value and unconditionally assigns the (32 bit) value to the (5 bit) QID field without masking. Fix priority assignment by only setting the AS_QID/AS_PRI flag when a valid value is passed, and properly mask the value to not overflow the QID/PRI field. For RTL839x, also assign the priority to the right part of the frame header. Counting from the leftmost bit, AS_PRI and PRI are in bits 36 and 37-39. The means they should be assigned to the third 16 bit value, containing bits 32-47.
