[dpdk-dev] [PATCH v2] ethdev: modifiy vlan_offload_set_t to return int

David Harton dharton at cisco.com
Fri Aug 25 15:33:19 CEST 2017


Some devices may not support or fail setting VLAN offload
configuration based on dynamic circurmstances 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.

Signed-off-by: David Harton <dharton at cisco.com>
---

*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.
