[PATCH 1/4] net/nfp: notify flower firmware about PF speed

[Chaoyong He]

From: Zerun Fu <zerun...@corigine.com>

When using flower firmware, the VF speed is obtained from the
firmware and the firmware get the VF speed from the PF.

But the previous logic does not notify the firmware about PF speed,
and this cause VF speed to be unavailable.

Fix this by add the logic of notify firmware about PF speed.

Fixes: e1124c4f8a45 ("net/nfp: add flower representor framework")
