Subject: net/mlx5e: Fix build break when CONFIG_XPS is not set
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Patch-mainline: v5.9-rc1
Git-commit: 8b5ec43d73dbdb427651caac5b76610ec0f5f298
References: jsc#SLE-15172

mlx5e_accel_sk_get_rxq is only used in ktls_rx.c file which already
depends on XPS to be compiled, move it from the generic en_accel.h
header to be local in ktls_rx.c, to fix the below build break

../drivers/net/ethernet/mellanox/mlx5/core/en_accel/en_accel.h:
In function ‘mlx5e_accel_sk_get_rxq’:

error: implicit declaration of function ‘sk_rx_queue_get’ ...
  int rxq = sk_rx_queue_get(sk);
            ^~~~~~~~~~~~~~~
