  Target Milestone: ---

- Unable to setup more than 1 TC
- Unable to enable TC strict priority

  testpmd> set vf tc tx min-bandwidth 0 0 (20,20,20,40)
  rte_pmd_i40e_set_vf_tc_bw_alloc(): Weight should be set for all 1 enabled
TCs.
  invalid vf_id 0 or bandwidth

  testpmd> set tx strict-link-priority 0 0x3
  rte_pmd_i40e_set_tc_strict_prio(): TC bitmap isn't the subset of enabled TCs
0x1.
