From: David Harton <dhar...@cisco.com>
Some devices may not support or fail setting VLAN offload
configuration based on dynamic circumstances so the
vlan_offload_set_t vector is modified to return an int so
the caller can determine success or not.
rte_eth_dev_set_vlan_offload is updated to return the
value provided by the vector when called along with restoring
the original offload configs on failure.
Existing vlan_offload_set_t vectors are modified to return
an int. Majority of cases return 0 but a few that actually
can fail now return their failure codes.
Finally, a vlan_offload_set_t vector is added to virtio
to facilitate dynamically turning VLAN strip on or off.

---
v5
* rebase on latest next-net
* add ETH_VLAN_FILTER_MASK mask check to virtio
v4
* Modified commit message heading
* Moved rel_note comments from ABI to API section
* Renamed locals of rte_eth_dev_set_vlan_offload from 'org*' to 'orig*'
v3
* Fixed a format error.
* Apologies...need to figure out why checkpatches.pl keeps saying
valid patch when I've got soft tabs.
v2
* Fixed a missed format error.
* Removed vlan offload vector call casts and replaced with checks
for return values.
v1
* This is an ABI breakage that has been previously negotiated
with Thomas and the proposed rel note change is included as well.
