Subject: [PATCH] net/ice: send driver version to firmware

The driver must send its version information to the firmware, so the firmware knows the driver is up. Otherwise, it will cause unexpected OS package downloading when multiple driver instances running on the same device.

Should the share code part and PMD part be separated into two patches?
