[huangtao]

I use peth driver with ixp1200, and meet this error message. 
this error will drop some output packet occasionally, who will tell 
me what is happend, thanks very much

this error is below:

$ insmod ue.o
$ insmod octmac.o
$ insmod giga_drv.o
$ rs_udebug
$ load
$ ping 1.2.1.1

then I meet the error message like that:

peth_start_xmit called
peth_start_xmit: new descriptor = 0
Bad descriptor 0, dropping outgoing packet
pethFreeDescriptor: descriptor = 0
pethFreeDescriptor: Bad descriptor 0
