[Xen-devel] ring buffer overflow

[David Xu <davidxu06@xxxxxxxxx>]

Hi,

Does anybody know whether the ring buffer between front end and back
end will suffer from overflow? I just wonder if the ring buffer will
be full and drop some packets when the Net I/O load is very heavy.
BTW, If I want to change the size of i/o ring buffer, how should I do?
I tried to reset the NET_TX_RING_SIZE and NET_RX_RING_SIZE in both
front end and back end, but it seems doesn't work. Thanks.

Regards,
Cong
