[U-Boot] questions about dp83848 on mpc8315e board

[du zhenhuan <dev_du@163.com>]

Hello, 
I'm using customized mpc8315e board with a PHY called DP83848 ,
I have changed tsec file to support DP83848, and link's status led is blinkging  after cable is connected to PC.
But when I set the ip etc  and to  ping  a PC , I got this error:


> ping 192.168.2.157
Trying eTSEC0


startup_tsec
 mii_parse_dp83848_bmsr:priv->duplexity:1,priv->speed:100Speed: 100, full duplex
Using eTSEC0 device
eTSEC0: tsec: tx error
eTSEC0: tsec: tx buffers full
ping failed; host 192.168.2.157 is not alive


I'm using MII interface connecting MPC8315e and DP83848,
what could be the possible reason for this ? Below is my MPC8315ERDB.h file.
