[PATCH v2] net/ncsi: Use real net-device for response handler

From: John Wang <hidden>
Date: 2020-12-23 05:56:16
Also in: lkml
Subsystem: ncsi library, networking [general], the rest · Maintainers: Samuel Mendoza-Jonas, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds

When aggregating ncsi interfaces and dedicated interfaces to bond
interfaces, the ncsi response handler will use the wrong net device to
find ncsi_dev, so that the ncsi interface will not work properly.
Here, we use the original net device to fix it.

Fixes: 138635cc27c9 ("net/ncsi: NCSI response packet handler")

v2:
  Use orig_dev instead of pt->dev
