Hello:

This patch was applied to netdev/net-next.git (main)
by Paolo Abeni [off-list ref]:

For CHECKSUM_PARTIAL skbs, validate_xmit_skb() resets
transport_header (inner_transport_header for encapsulated skbs)
from csum_start, but only after netif_skb_features() has called
ndo_features_check().

The hook can therefore see a transport_header left elsewhere by
the receive path, while ndo_start_xmit() sees the reset one. For
example, ip6_rcv_core() leaves it after the fixed header of
forwarded IPv6 packets with destination options or a routing
header, and seg6, rpl and ioam6 point it at the header they insert.

[...]

You are awesome, thank you!
