Subject: [PATCH] event/cnxk: add preliminary Tx queue depth check
Date: Tue, 16 Aug 2022 21:05:45 +0530 [thread overview]
Message-ID: <20220816153545.7536-1-pbhagavatula@marvell.com> (raw)
From: Pavan Nikhilesh <pbhagavatula@marvell.com>
add preliminary Tx queue depth check and return on failure.
Once the check passes, tx_adapter_enqueue() function becomes
a blocking call till it succeeds.
