Is there any advantage to use TUN/TAP interface ?
As 802.11bbn also uses TUN/TAP interface.
But I think in the tun/tap performance degrades as we send the packet
back
to user process?
Therefore I compare results with benchmark_xx.py in /ofdm with
tunnel.py
in /ofdm.
In results benchmark_xx.py do not give consistent throughput (i.e. it
varies on channel) but tunnel.py gives 100% throughput irrespective of
channel
Will there be any valid reason for this ?
If I want to implement 2-way communication in USRP should I use TUN/TAP
interface?

Tun/tap is a convenient way to get access to the network stack from
userspace. Unfortunately the benchmark* apps abuse tun/tap as a mac
layer, which is precisely the wrong thing to do.
For example:
(if you wait a few days, there will be some sweet work released with MAC
layer + message passing in GRC. Stay tuned…)

Cool.
How can I get this information at that time?
