Subject: net/mlx5e: Allocate virtually contiguous memory for reps structures
Patch-mainline: v5.19-rc1
Git-commit: 597c112326197786abcc3a38090b08856bf860af
References: jsc#PED-1549

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