[][kernel][common][eth][Remove phylink set line rate to maximum]

[Description]
Remove phylink set line rate to maximum.
For tunnel HW offload path, we expect throughput higher is better. So,
we didn't set rate limit on QDMA qid=12. However, when LAN throughput is
much larger than WAN, packets will drop.

We tried to get link rate and set corresponding rate limit on QDMA queue
12 to solve this problem.

Without this patch, mac always returns line rate as link rate.
