Subject: [Linux-usb-users] Issue of g_ether runing on my udc driver...

Hi all,

I am just working on an udc driver of our custom
board,which is EP9302(ARM9) + ISP1581(high speed). I
need to make the device together with ether.c as a
RNDIS to windows host, normall XP. Now the driver
seems to be working, the windows host can recognize
the "Linux USB Ethernet/RNDIS Gadget #2" and install
the "linux.inf" driver successfully. 

But when I try to "ping" the board from windows host
with a large dataload,like 8192 bytes:

ping 192.168.0.2 -l 8192 -n 100

some requests are always time-out. If I change
dataload size to 1500 or below, the requests are 100%
echoed.

So I wonder if there is anything i can do to correct
this problem ? Has anybody met it before?

The linux tree I am using is cirrus-realeased, which
is 2.6.8.1 based(seems old).


thx!
