Subject: net: force bridge module(s) to be GPL
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4fb019a01a7f67342d4a88d26c0817afe392c669;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

net: force bridge module(s) to be GPL

The only valid usage for the bridge frame hooks are by a
GPL components (such as the bridge module).
The kernel should not leave a crack in the door for proprietary
networking stacks to slip in.
