Subject: [PATCH net-next 7/7] bnxt_en: Add warning message about disallowed speed change

From: Sreekanth Reddy <sreekanth.reddy@...adcom.com>

Some chips may not allow changing default speed when dual rate
transceivers modules are used. Firmware on those chips will
indicate the same to the driver.

Add a warning message when speed change is not supported
because a dual rate transceiver is detected by the NIC.
