Hi Helin,

Thanks for acknowledging.

This mail to explain how important it is to configure his mailer.
You need to quote the original mail so we can quickly find what
you have replied.
It is also a problem for patchwork as it creates a new entry:
	http://dpdk.org/dev/patchwork/patch/23300/
because it thinks it is a new patch.
So your ack is not registered in the original patch entry:
	http://dpdk.org/dev/patchwork/patch/23298/

Please share this explanation, thanks
