[PATCH v2 0/2] net/i40e: Fix aarch32 build and vector flag setting

[Ciara Loftus]

Fix two issues present on the i40e driver that were introduced by the tx path selection series:
1. Fix a build failure on 32-bit arm caused by an unused function.
2. Ensure that the vector flag is unset when the scalar path is chosen.

If possible both can be squashed into the commit they fix on next-net-intel.

[PATCH v2 2/2] net/i40e: unset vector flag when scalar path is chosen

[Ciara Loftus]

The tx_vec_allowed flag should be set to false if a scalar Tx path is
chosen.
