[ Upstream commit 9e5ffed37df68d0ccfb2fdc528609e23a1e70ebe ]
Looks like when BPF support was added by commit d3b18ad31f
("tls: add bpf support to sk_msg handling") and
commit d829e9c411 ("tls: convert to generic sk_msg interface")
it broke/removed the support for in-place crypto as added by
commit 4e6d47206c ("tls: Add support for inplace records
encryption").
The inplace_crypto member of struct tls_rec is dead, inited
to zero, and sometimes set to zero again. It used to be
set to 1 when record was allocated, but the skmsg code doesn't
seem to have been written with the idea of in-place crypto
in mind.
Since non trivial effort is required to bring the feature back
and we don't really have the HW to measure the benefit just
remove the left over support for now to avoid confusing readers.
