ring_{rx,tx}: verbose: output version and v3 specific info
Kevin says:
With netsniff-ng 0.5.8-rc2+, when I run the below packet capture
session, the output seems to imply that 64K of memory is being
allocated per frame, which does not look like what I want since my
interface MTU is only 1500. This appears to be severely limiting
the number of frames I can fit into my packet capture ring.
As TPACKET_V3 is used in capturing to pcap files, frames are written
continuously to the ring, thus the above will give a wrong impression
to the user. Therefore, output such information in verbose mode
differently when TPACKET_V3 is being used, as it works block-wise.
