Using UDP protocol implementation real-time image data to PC to upload, phy chip interface for RTL8211E - VL (RGMII), wiresharp caught on the system about 5 s electricity only upload data, can interrupt transmission, while the ILA caught the FPGA has been issued, so data continuingly after a few seconds to pull out the same interrupt; Before the hardware version of the use of the phy is RTL8211EG (GMII), receive completely normal, don't understand what the reason, ask for advice
