[PATCH V4 mlx5-next 02/13] net/mlx5: Reuse exported virtfn index function call

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Leon Romanovsky <leonro@xxxxxxxxxx>

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