This patchset adds the special "remote" feature to the tap PMD, that
actually enables capturing traffic from another netdevice. This is
especially useful to get packets into the DPDK app, when the remote
netdevice has no DPDK support.
The "remote" feature requires flow API support as flow rules will be
configured on the remote netdevice for redirection, using the same
mechanism.
This series applies on top of:
[PATCH 0/4] net/tap: support flow API
v2 changes:
- rebase on top of updated "net/tap: support flow API"
- fix implicit flow flush when closing the netdevices
v3 changes:
- memset(0) for remote_iface in rte_pmd_tap_probe()
- use snprintf instead of strncpy to correctly handle terminating \0
v4 changes:
- rebase on top of updated "net/tap: support flow API"
- use only a single patch now as MTU, MAC and flags can be easily managed
with tap_ioctl()
