Dear All:
I am using linux=20 2.6.14.5 (with many modification) and MPC8548.
Sometimes(very rare)=20 the nic will boot up with rx problem. (tx is just fine)
I see pkts are all dropped in chip but = no any RX=20 or BSY interrupt are ever raised.
(Receive Drop Counter is = increased)
If=20 I down and up the nic, the problem will=20 gone.
Any suggestion is welcome.=20 Thanks.
