In future submissions please formation your Subject line properly.
First, there should always be a space character after the ":" following
the subsystem prefix.
Next, "net-next" belongs inside of the '' so "[PATCH net-next N/M] ".
However, when you have a single patch, there is no reason to give the
"N/M" part, so you can just drop it in this situation.
Please also capitalize the text after the subsystem prefix string.
Therefore this Subject must be formatted exactly like this:
Subject: "[PATCH net-next] hinic: Optimize RX refill buffer mechanism"
But meanwhile you must address the feedback given to you by Neil and myself.
You absolutely MUST NOT receive a RX packet if you cannot successfully
allocate a replacement buffer for the RX ring in that slot. It allows
the RX ring to become empty, which many cards respond to by hanging.
It would really serve you poorly if you continue to ignore our
feedback because addressing it is a requirement before we will be able
to consider integrating your work.
