From c090451633f89c292316e928f970d082d7e8295f Mon Sep 17 00:00:00 2001 From: Maxim Mikityanskiy Date: Mon, 31 Jan 2022 17:28:40 +0200 Subject: [PATCH] net/mlx5e: Remove assignment of inline_hdr.sz on XDP TX When MPWQE is disabled, mlx5e_open_xdpsq prefills the common fields of WQEs in the XDP SQ to save time when sending packets. One of such fields is eseg->inline_hdr.sz, which can be either 0 or MLX5E_XDP_MIN_INLINE, depending on the inline mode of the SQ. The inline mode can't change during the lifetime of the SQ, so setting this field again in mlx5e_xmit_xdp_frame is redundant. Moreover, the xmit function only sets it to MLX5E_XDP_MIN_INLINE, but not to 0 in the other case. This commit removes the redundant assignment in mlx5e_xmit_xdp_frame.
