U-Boot: Using 10M half duplex on T1024 gives Rx error and never recovers

I'm trying to use the FM1 DTSEC4 interface in RGMII mode configured as 10Mb half duplex to transfer a big data file (180MB) in U-Boot, but the transfer fails with the error "FM1@DTSEC4: Rx error" and the interface will only recover after a processor reset. An initial analysis on the reason for the error shows that the "Frame Size Error" flag of a faulty RxBD caused the problem.


Shouldn't the U-Boot FMAN driver recover in such situations?
