net/mlx5e: Update UDP fields of the SKB for GSO first (55461000) · Commits · 戴 / test

mlx5e_udp_gso_handle_tx_skb updates the length field in the UDP header in case of GSO. It doesn't interfere with other offloads, so do it first to simplify further restructuring of the code. This way we'll make all independent modifications to the SKB before starting to work with WQEs. Signed-off-by:
