Subject: [PATCH net 1/6] qed: Fix EQ full firmware assert.
Date: Wed, 6 Feb 2019 14:43:42 -0800 [thread overview]
Message-ID: <20190206224347.17054-2-manishc@marvell.com> (raw)
In-Reply-To: <20190206224347.17054-1-manishc@marvell.com>
When slowpath messages are sent with high rate, the resulting
events can lead to a FW assert in case they are not handled fast
enough (Event Queue Full assert). Attempt to send queued slowpath
messages only after the newly evacuated entries in the EQ ring
are indicated to FW.
