ipv6: Fix IPsec pre-encap fragmentation check
The IPv6 IPsec pre-encap path performs fragmentation for tunnel-mode
packets. That is, we perform fragmentation pre-encap rather than
post-encap.
A check was added later to ensure that proper MTU information is
passed back for locally generated traffic. Unfortunately this
check was performed on all IPsec packets, including transport-mode
packets.
What's more, the check failed to take GSO into account.
The end result is that transport-mode GSO packets get dropped at
the check.
This patch fixes it by moving the tunnel mode check forward as well
as adding the GSO check.
Fixes: dd767856a36e ("xfrm6: Don't call icmpv6_send on local error")
