Subject: [PATCH ipsec 2/3] esp: Fix BEET mode inter address family tunneling on GSO
Date: Mon, 7 Mar 2022 13:11:40 +0100	[thread overview]
Message-ID: <20220307121141.1921944-3-steffen.klassert@secunet.com> (raw)
In-Reply-To: <20220307121141.1921944-1-steffen.klassert@secunet.com>

The xfrm{4,6}_beet_gso_segment() functions did not correctly set the
SKB_GSO_IPXIP4 and SKB_GSO_IPXIP6 gso types for the address family
tunneling case. Fix this by setting these gso types.

Fixes: 384a46ea7bdc7 ("esp4: add gso_segment for esp4 beet mode")
Fixes: 7f9e40eb18a99 ("esp6: add gso_segment for esp6 beet mode")
