[dpdk-dev] [PATCH v2 1/2] bus/fslmc: don't log error for other devices

[Stephen Hemminger]

When fslmc is built as part of a general distribution, the
bus code will log errors when other devices are present.

This could confuse users it is not an error.

[dpdk-dev] [PATCH v2 2/2] bus/fslmc: remove unneeded strdup

[Stephen Hemminger]

The fslmc bus code was duplicating the device name and
doing extra initialization. The code can be simplified
to just use the device name directly.

Compile tested only; do not have this hardware.
