> Subject: [PATCH] net/mlx5: fix order of lines in loop
>
> Function flow_dv_zero_encap_udp_csum() uses a while loop to iterate over
> vlan items in flow rule.
> Pointer next_hdr is incremented to the next item before it is used, so the
> first
> item is skipped.
>
> This patch moves the incrementing of next_hdr to the correct place.

> Fixes: bf1d7d9a033a ("net/mlx5: zero out UDP checksum in encapsulation")
