Subject: bridge: change console message interface
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=28a16c97963d3bc36a2c192859f6d8025ef2967a;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

bridge: change console message interface

Use one set of macro's for all bridge messages.

Note: can't use netdev_XXX macro's because bridge is purely
virtual and has no device parent.
