Subject: [PATCH net-next] Revert "ipv6: Initial skb->dev and skb->protocol in ip6_output"

From: Chenbo Feng <fengc@...gle.com>

This reverts commit 97a7a37a7b7b("ipv6: Initial skb->dev and
skb->protocol in ip6_output") since it does not handles the
skb->dev assignment inside ip6_fragment() code path properly.
Need to rework and upload again

Fixes: 97a7a37a7b7b("ipv6: Initial skb->dev and skb->protocol in ip6_output")
