Subject: [PATCH] common/cnxk: fix aura offset
Date: Mon, 24 Mar 2025 11:39:35 +0530	[thread overview]
Message-ID: <20250324060935.2644402-1-nkishor@marvell.com> (raw)
In-Reply-To: <20250304052217.796506-1-nkishor@marvell.com>

Aura field width has reduced from 20 bits in cn10k/cn9k
to 17 bits in cn20k. Adjust the setting of aura offset in
NPA_LF_POOL_OP_INT register accordingly based on the platform.

Fixes: 620fc02bf7eb ("common/cnxk: accommodate change in aura field width")
