In esp6_init_state() for beet mode when x->sel.family != AF_INET6:
x->props.header_len = sizeof(struct ip_esp_hdr) +
crypto_aead_ivsize(aead) + IPV4_BEET_PHMAXLEN +
(sizeof(struct ipv6hdr) - sizeof(struct iphdr))
In xfrm6_beet_gso_segment() skb->transport_header is supposed to move
to the end of the ph header for IPPROTO_BEETPH, so if x->sel.family !=
AF_INET6 and it's IPPROTO_BEETPH, it should do:
skb->transport_header -=
(sizeof(struct ipv6hdr) - sizeof(struct iphdr));
skb->transport_header += ph->hdrlen * 8;
And IPV4_BEET_PHMAXLEN is only reserved for PH header, so if
x->sel.family != AF_INET6 and it's not IPPROTO_BEETPH, it should do:
skb->transport_header -=
(sizeof(struct ipv6hdr) - sizeof(struct iphdr));
skb->transport_header -= IPV4_BEET_PHMAXLEN;
Thanks Sabrina for looking deep into this issue.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
