Subject: [PATCH 18/23] net/nfp: add check for numbers of VF representor port
Date: Wed, 19 Jun 2024 17:58:25 +0800	[thread overview]
Message-ID: <20240619095830.3479757-19-chaoyong.he@corigine.com> (raw)
In-Reply-To: <20240619095830.3479757-1-chaoyong.he@corigine.com>

From: Peng Zhang <peng.zhang@corigine.com>

When the number of VF representor ports is bigger than
the number of VF ports, there will be segment fault.

Fix this by adding the check logic.

Fixes: e1124c4f8a45 ("net/nfp: add flower representor framework")
