Subject: [PATCH 5.16 0716/1017] netfilter: egress: Report interface as outgoing

From: Phil Sutter <phil@....cc>

[ Upstream commit d645552e9bd96671079b27015294ec7f9748fa2b ]

Otherwise packets in egress chains seem like they are being received by
the interface, not sent out via it.

Fixes: 42df6e1d221dd ("netfilter: Introduce egress hook")
