Checks
Commit Message
testpmd will occur infinite loops when device hotplug remove.
We can fix the issue by using the pci generic remove function
Fixes: ac89d46096d5 ("net/i40e: release port upon close")
Signed-off-by: Di ChenxuX <chenxux.di@intel.com>
v3:
reverted the code about i40e_vf_representor_uninit.
v2:
