i have some problems with using fec device on my custom 8250 board
while sending a lot of data (at least 300MB) through this device causes
lack of memory
sending same amount of data through loopback works fine

It looks like skb leaks in the driver. Probably in TX path.

Could you send me by private e-mail source code for ethernet driver in
question or provide a URL.

I'm not a 8250 guy, but I'll try to look at it :)
