drivers/net/8139too.c:
/* In case of an RxFIFOOver we must also clear the RxOverflow
bit to avoid dropping frames for ever. Believe me, I got a
lot of troubles copying huge data (approximately 2 RxFIFOOver
errors per 1GB data transfer).
The following is written in the 'p-guide.pdf' file (RTL8139(A/B)
Programming guide V0.1, from 1999/1/15) on page 9 from REALTEC.
-----------------------------------------------------------
2. RxFIFOOvw handling:
When RxFIFOOvw occurs, all incoming packets are discarded.
Clear ISR(RxFIFOOvw) doesn't dismiss RxFIFOOvw event. To
dismiss RxFIFOOvw event, the ISR(RxBufOvw) must be written
with a '1'.
-----------------------------------------------------------
Unfortunately I was not able to find any reason for the
RxFIFOOver error (I got the feeling this depends on the
-> CPU speed, lower CPU speed --> more errors).
After clearing the RxOverflow bit the transfer of the
packet was repeated and all data are error free transfered */
