to capture all passing packets through a network the nic needs to be in __ mode?
promiscuous
on wired broadcast and wireless lans, to capture unicast traffic between other machines, the network adapter capturing the traffic must be in promiscuous mode. on wireless lans, even if the adapter is in promiscuous mode, packets not for the service set the adapter is configured for are usually ignored. to see those packets, the adapter must be in monitor mode. no special provisions are required to capture multicast traffic to a multicast group the packet analyzer is already monitoring, or broadcast traffic.
packet analyzer
the use of unicast and the limited amount of multicast packets, combined with asynchronous notifications, enables links that are not actively passing packets to be put into reduced power states, which allows better power management.









































section::::overview.:data encoding.









































the ""superspeed"" bus provides for a transfer mode at a nominal rate of 5.0 gbit/s, in addition to the three existing transfer modes. accounting for the encoding overhead, the raw data throughput is 4 gbit/s, and the specification considers it reasonable to achieve 3.2 gbit/s (400 mb/s) or more in practice.
