[v2] net/i40e: disable source pruning
Checks
Commit Message
VRRP advertisement packets are dropped on i40e PF devices because
when a MAC address is added to a device, packets originating from
that MAC address are dropped.
This patch adds a devarg to support disabling source pruning to work
around above issue.

+- ``Disable source pruning on PF`` (default ``not disabled``)
+
+ When a MAC address is added to a device, packets originating from that MAC
+ address will be dropped for source pruning. To disable source pruning on PF
+ we can add ``devargs`` parameter ``disable_source_pruning=[0,1]`` and set its
+ value to 1, for example::
+
+ -a 84:00.0,disable_source_pruning=1
