When the link is down, the link speed returned by ethtool is
UINT32_MAX and the link status is 0.
In this case, the DPDK ethdev link speed should be set to
ETH_SPEED_NUM_NONE.
Otherwise since link speed is non-zero but link status is zero, this
is an inconsistent situation and -EAGAIN is returned,

When the link is down, mlx5 kernel driver reports the link speed as -1
(UNKNOWN_SPEED). We need turn it to 0 for such case, otherwise, it
will be re-queried again due to the link_speed is not 0, due to following
code:
1201 if (((link->link_speed == 0) && link->link_status) ||
1202
