[PATCH 5/5] net: renesas: rswitch: remove speed from gwca structure
Posted by Nikita Yushchenko 1 year, 2 months ago
This field is set but never used.

GWCA is rswitch CPU interface module which connects rswitch to the
host over AXI bus. Speed of the switch ports is not anyhow related to
GWCA operation.

I tried grepping the code and didn't find any other users either.

This one also could be a cleanup that goes to next since there doesn't
appear to be any user visible bug.
