net/mlx5e: kTLS, Fix napi sync and possible use-after-free
net/mlx5e: Use synchronize_rcu to sync with NAPI
net/mlx5e: Use RCU to protect rq->xdp_prog 

all patches are applied cleanly beside 
1182f3659357 net/mlx5e: kTLS, Add kTLS RX HW offload support
that has one hunk rejected in 
file: drivers/net/ethernet/mellanox/mlx5/core/en_main.c
function: mlx5e_init_nic_rx
the rejection is caused by and extra #ifdef statement 
inserted by commit f4aebbfb56ed0c186adbeb2799df836da50f78e3 
here we just need to add manually the needed lines.
