[PATCH 5.4 47/51] net: use netif_is_bridge_port() to check for IFF_BRIDGE_PORT

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

From: Julian Wiedmann <jwi@linux.ibm.com>

[ Upstream commit 2e92a2d0e450740ebe7e7a816162327ad1fde94b ]

Trivial cleanup, so that all bridge port-specific code can be found in
one go.
