> Subject: [PATCH v4 21/30] net/ice/base: fix segment in remove existing RSS
> rule
>
> Before this patch, RSS tunneled rules can not be destroyed at runtime.
> This is because it can not find the existing matching profile for tunnels.
> segs[0] should always be zero and all matched, segs[1] for inner part.
> It only construct one segment.
>
> This patch modifies construct segment in ice_rem_rss_cfg_sync() to match
> ice_add_rss_cfg_sync().
>
> Fixes: 75bc2ea04af4 ("net/ice/base: packet encapsulation for RSS")
