Subject: [net-next 04/16] net/mlx5: Allocate virtually contiguous memory in vport.c

From: Saeed Mahameed <[email-masked]>
Date: Tue, 17 May 2022 23:49:26 -0700

From: Tariq Toukan <[email-masked]>

Physical continuity is not necessary, and requested allocation size might
be larger than PAGE_SIZE.
Hence, use v-alloc/free API.
