主题: [PATCH 7/7] net/ice: pin outer Ethertype for L2TPv2 flow rules

L2TPv2 flow rules do not include the outer Ethertype in the input set, so a rule created for outer IPv6 also matches packets with outer IPv4 (and vice versa). The hardware profile cannot distinguish the two families because nothing in the match key differentiates them.

Add ICE_INSET_ETHERTYPE to input_set_o and set ext_data.ether_type to
0x0800 or 0x86DD based on the outer L3 item, so the profile includes the Ethertype field and rejects cross-family mismatches.
