The Marvell switches allow the hash algorithm for MAC addresses in the address translation unit to be configured. Add support to the DSA core to allow DSA drivers to make use of devlink parameters, and allow the ATU hash to be get/set via such a parameter.

Document the parameter. .../networking/devlink-params-mv88e6xxx.txt | 6 + MAINTAINERS | 1 + drivers/net/dsa/mv88e6xxx/chip.c | 134 +++++++++++++++++- drivers/net/dsa/mv88e6xxx/chip.h | 4 + drivers/net/dsa/mv88e6xxx/global1.h | 3 + drivers/net/dsa/mv88e6xxx/global1_atu.c | 32 +++++ include/net/dsa.h | 23 +++ net/dsa/dsa.c | 48 +++++++ net/dsa/dsa2.c | 7 +- 9 files changed, 256 insertions(+), 2 deletions(-) create mode 100644 Documentation/networking/devlink-params-mv88e6xxx.txt -- 2.23.0
