This is a pure rename without any changes. It makes maintaining bgmac simpler and will hopefully make adding new kernel a bit easier. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>

Subject: [PATCH 2/3] bgmac: Add support for ethtool statistics
|
|
|
|
Read the statistics from the BGMAC's builtin MAC and return them to
|
|
user-space using the standard ethtool helpers.
