         2 x86pc won't ping success to imx6q(at 65000B package, but small packet is ok)


         it modifes mac driver in vxworks6.9 refer to linux kernel, although it ping failed in top four packget, and then it 's ok( 65000B package), why?

         x86 connect imx6q, it's readch 18MB/s or 40MB/s after ping big pack success, also firstly it's not stable, imx6q power on, x86pc connect it, sometime it works small bandwidth(<1MB), and then it reaches 18 or 40MB. it don't occur the appearnce that no data communicates.
