[PATCH v2 net-next 04/12] net: ethtool: fix __ethtool_dev_mm_supported() implementation

From: Vladimir Oltean
Date: Sun Feb 19 2023 - 08:54:01 EST


The MAC Merge layer is supported when ops->get_mm() returns 0.
The implementation was changed during review, and in this process, a bug
was introduced.
