Subject: [PATCH v4 12/28] net/cnxk: add barrier after meta batch free in scalar
Date: Sun, 8 May 2022 11:56:00 +0530
Message-ID: <20220508062616.3398-12-ndabilpuram@marvell.com> (raw)
In-Reply-To: <20220508062616.3398-1-ndabilpuram@marvell.com>

Add barrier after meta batch free in scalar routine when
lmt lines are exactly full to make sure that next LMT line user
in Tx only starts writing the lines only when previous stoerl's
are complete.

Fixes: 4382a7ccf781 ("net/cnxk: support Rx security offload on cn10k")
