Subject: [PATCH net-next 1/3] net: dsa: Split platform data to header file
Instead of having net/dsa.h contain both the internal switch tree/driver
structures, split the relevant platform_data parts into
include/linux/platform_data/dsa.h and make that header be included by
net/dsa.h in order not to break any setup. A subsequent set of patches
will update code including net/dsa.h to include only the platform_data
header.
