[PATCH net-next v2 15/35] net: fman: Move initialization to mac-specific files
Sean Anderson
sean.anderson at seco.com
Tue Jun 28 15:13:44 PDT 2022
This moves mac-specific initialization to mac-specific files. This will
make it easier to work with individual macs. It will also make it easier
to refactor the initialization to simplify the control flow. No
functional change intended.
Signed-off-by: Sean Anderson <sean.anderson at seco.com>

Changes in v2:
- Fix prototype for dtsec_initialization
