Hmmm, Jiri this doesn't compile?
CC [M] drivers/net/ethernet/intel/iavf/iavf_main.o
drivers/net/ethernet/intel/iavf/iavf_main.c: In function ‘iavf_setup_tc_block_cb’:
drivers/net/ethernet/intel/iavf/iavf_main.c:3089:7: error: implicit declaration of function ‘tc_cls_can_offload_basic’; did you mean ‘tc_cls_common_offload_init’? [-Werror=implicit-function-declaration]
if (!tc_cls_can_offload_basic(adapter->netdev, type_data))
Maybe it does depend upon something in the tc filter patch series?
