Subject: [PATCH V7 mlx5-next 02/15] net/mlx5: Reuse exported virtfn index function call
Date: Mon, 7 Feb 2022 19:22:03 +0200	[thread overview]
Message-ID: <20220207172216.206415-3-yishaih@nvidia.com> (raw)
In-Reply-To: <20220207172216.206415-1-yishaih@nvidia.com>

From: Leon Romanovsky <leonro@nvidia.com>

Instead open-code iteration to compare virtfn internal index, use newly
introduced pci_iov_vf_id() call.
