Adds following tests:
1. AF_XDP SKB mode
d. Bi-directional Sockets
Configure sockets as bi-directional tx/rx sockets, sets up fill
and completion rings on each socket, tx/rx in both directions.
Only nopoll mode is used
2. AF_XDP DRV/Native mode
d. Bi-directional Sockets
* Only copy mode is supported because veth does not currently support
zero-copy mode

Adds following tests:
1. AF_XDP SKB mode
c. Socket Teardown
Create a Tx and a Rx socket, Tx from one socket, Rx on another.
Destroy both sockets, then repeat multiple times. Only nopoll mode
is used
2. AF_XDP DRV/Native mode
c. Socket Teardown
* Only copy mode is supported because veth does not currently support
zero-copy mode

Adds following tests:
2. AF_XDP DRV/Native mode
Works on any netdevice with XDP_REDIRECT support, driver dependent.
Processes packets before SKB allocation. Provides better performance
than SKB. Driver hook available just after DMA of buffer descriptor.
a. nopoll
b. poll
* Only copy mode is supported because veth does not currently support
zero-copy mode

Adds following tests:
1. AF_XDP SKB mode
Generic mode XDP is driver independent, used when the driver does
not have support for XDP. Works on any netdevice using sockets and
generic XDP path. XDP hook from netif_receive_skb().
a. nopoll - soft-irq processing
b. poll - using poll() syscall
