Subject: [PATCH 4/7] net/cnxk: fix descriptor count update on reconfig
Date: Wed, 28 May 2025 17:21:19 +0530	[thread overview]
Message-ID: <20250528115122.24052-4-rbhansali@marvell.com> (raw)
In-Reply-To: <20250528115122.24052-1-rbhansali@marvell.com>

In Rx queue setup, input descriptors count is updated as per
requirement, and stored. But during port reconfig , this
descriptor count will change again in rx queue setup.
Hence, will need to store the initial input descriptor count.

Fixes: a86144cd9ded ("net/cnxk: add Rx queue setup and release")
