They are on different machines. My LNS is a gentoo and my BGP router a
FreeBSD.

The offloading on linux doesn’t change anything, but disabling it on the
router made tunnel going up instantaneously.

root@bgp-adsl:~ # ifconfig vtnet2 -rxcsum -txcsum -tso -lro

Thanks for the hint!

BTW, my other LNS uses xl2tpd (and a patched PPP plus kea for IPv6) and
wasn’t impacted. I’m not enough skilled to see the differences in the
code.
