Subject: [PATCH for-next 15/20] RDMA/rtrs: Do not reset hb_missed_max after re-connection
Date: Mon,  3 May 2021 13:48:13 +0200	[thread overview]
Message-ID: <20210503114818.288896-16-gi-oh.kim@ionos.com> (raw)
In-Reply-To: <20210503114818.288896-1-gi-oh.kim@ionos.com>

From: Gioh Kim <gi-oh.kim@cloud.ionos.com>

When re-connecting, it resets hb_missed_max to 0.
Before the first re-connecting, client will trigger re-connection
when it gets hb-ack more than 5 times. But after the first
re-connecting, clients will do re-connection whenever it does
not get hb-ack because hb_missed_max is 0.

There is no need to reset hb_missed_max when re-connecting.
hb_missed_max should be kept until closing the session.
