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 1/3] net: bgmac: Fix SOF bit checking
|
|
|
|
We are checking for the Start of Frame bit in the ctl1 word, while this
|
|
bit is set in the ctl0 word instead. Read the ctl0 word and update the
|
|
check to verify that.
|
|
|
|
Fixes: 9cde94506eac ("bgmac: implement scatter/gather support")
