[PATCH 1/8] lpfc: Fix FCoE speed reporting

[James Smart <jsmart2021@gmail.com>]

Current Link speed was shown as "unknown" in sysfs for FCoE ports
In this scenario, the port was working in 20G speed, which happens to
not be a speed handled by the driver.

Add support for all possible link speeds that could get reported from
port_speed field in link state ACQE.

Additionally, as supported_speeds can't be manipulated via the fcoe driver
on a converged ethernet port (it must be managed by the nic function),
don't fill out the supported_speeds field for the fc host object in sysfs.

Revise debug logging to report Link speed mgmt valuess.
