Subject: [PATCH v2 12/19] common/cnxk: fix max number of SQB bufs in clean up
Date: Mon, 13 Oct 2025 12:29:42 +0530	[thread overview]
Message-ID: <20251013065949.200414-12-ndabilpuram@marvell.com> (raw)
In-Reply-To: <20251013065949.200414-1-ndabilpuram@marvell.com>

From: Sunil Kumar Kori <skori@marvell.com>

By default, SQB pool is created with max (512 buffers) +
extra threshold buffers and aura limit is set to 512 + thr.

But while clean up, aura limit is reset to MAX (512 buffers)
only before destroying the pool.

Hence while destroying the pool, only 512 buffers are cleaned
from aura and extra threshold buffers are left as it is.

At later stage if same SQB pool is created then H/W
throws error for extra threshold buffers that it is already
in pool.

Fixes: 780f90e951a5 ("common/cnxk: restore NIX SQB pool limit before destroy")
