[1/2] test/link_bonding: disable HW CRC strip by default.
Checks
Commit Message
Since the tested virtual device has no capacity of HW CRC offload,
disable it for the link bonding test by default. Otherwise, it will
cause test unexpected failure.

Hi Phil,
There is a patch to add DEV_RX_OFFLOAD_CRC_STRIP to virtual devices [1] and
there is another under development to remove old offload API [2], those both
looks like can replace your patch when merged.

Hi Ferruh,
Thanks for you patch.

"And DEV_RX_OFFLOAD_CRC_STRIP has been added to virtual drivers since
they don't use CRC at all, when an application requires this offload
virtual PMDs should not return error."
I think you have ignored virtual_pmd driver. Since test_link_bonding use test/virtual_pmd for the testing device.
I unstreamed a patch for this defect. Please review it.
