In ice_txd_enable_offload(), when set tunnel packet Tx checksum
offload enable, td_offset should be set with outer l2/l3 len instead
of inner l2/l3 len.

This patch fix the bug that the checksum engine can forward tunnle
packets.

Fixes: 28f9002ab67f ("net/ice: add Tx AVX512 offload path")

The tunnel packets is missing some information after Tx forwarding.

In ice_txd_enable_offload, when set tunnel packet Tx checksum
offload enable, td_offset should be set with outer l2/l3 len instead
of inner l2/l3 len.

In ice_txd_enable_checksum, td_offset should also be set with outer
l3 len.

This patch fix the bug that the checksum engine can forward Ipv4/Ipv6
tunnel packets.

Fixes: 28f9002ab67f ("net/ice: add Tx AVX512 offload path")
Fixes: 17c7d0f9d6a4 ("net/ice: support basic Rx/Tx")

Is this fix also cover IPv4 Tx checksum offload? 
Please refine the title to reflect what exactly the patch does if necessary.

Btw, could you also check if any fix needed in ice_txd_enable_checksum?
I saw inconsistent offset configure on l3_len between scaler path and vector path.
Its better to always keep them identical.

I checked code in ice_txd_enable_checksum, and it should also be fixed here. I will send a new patch of v2.
