Hello,
Can we go odp_pktio_open() return default interface provided by
implementation?
For linux-generic we already have environment variables to select
between mmap and raw sockets.
Also we can add hint what is default interface name.
Like:
export ODP_PKIO_DEFAULT_DEV="eth0"
And if this variable is not exported it might be eth0, eth1, then eth2.
Or first device found in list returned by ioctl.
Reason is to add to CUNIT tests coverage for functions which need pktio.
It makes more sense to have an API to request available pktio interfaces
and their characteristics. So application can pick one of them instead
of default.
But as Bala mentioned for tests you need loopback interface, but not a
real one.
