Subject: net/mlx5e: Fix check if netdev is bond slave
From: Maor Dickman <maord@xxxxxxxxxx>
[ Upstream commit 219b3267ca102a35092f5998921a9e6f99074af2 ]
Bond events handler uses bond_slave_get_rtnl to check if net device
is bond slave. bond_slave_get_rtnl return the rcu rx_handler pointer
from the netdev which exists for bond slaves but also exists for
devices that are attached to linux bridge so using it as indication
for bond slave is wrong.
Fix by using netif_is_lag_port instead.
