[realtek] [Question] Oversized Ethernet frame.
Tue, 03 Jul 2001 17:46:42 +0900
Sorry my poor English.
We are using version 1.08 of rtl8139.c (RTL8139C), and testing the machine.
But that version driver indicates below message and eth5 stop responding:
"eth5: Oversized Ethernet frame, status 39393939!"
It seems that driver proceeds in the following process:
A. IntrStatus is either 0x51 or 0x30, so driver sets
the value of RxBufAddr into RxBufPtr in rtl8129_interrupt.
B. But packets don't reach Rx Buffer, rtl8129_rx returns right away.
(Because BufEmpty bit is checked.)
C. rtl8129_rx is called again, but BufEmpty bit is cleared ,
and reads the wrong rx_status value.
D. rx_status is wrong, so print above message.
I have some questions:
Q1. This problem is solved in the latest driver ?
Q2. Do you have any patch solving this problem ?
Q3. If Q1's answer is No, are you going to correct this problem ?
