[ Upstream commit 28b0865714b315e318ac45c4fc9156f3d4649646 ]
When the returned speed from __ethtool_get_link_ksettings() is
SPEED_UNKNOWN this will lead to reporting a wrong speed and width for
providers that uses ib_get_eth_speed(), fix that by defaulting the
netdev_speed to SPEED_1000 in case the returned value from
__ethtool_get_link_ksettings() is SPEED_UNKNOWN.
Fixes: d41861942fc5 ("IB/core: Add generic function to extract IB speed from
netdev")
