重新购买了一个雷电转网卡的新设备之后，这个日志消失了

- mac 的上的问题
- iftop 有一个选项 ```txt 🧀 iftop -h iftop: display bandwidth usage on an interface by host
Synopsis: iftop -h | [-npblNBP] [-i interface] [-f filter code] [-F net/mask] [-G net6/mask6]
-h display this message -n don’t do hostname lookups -N don’t convert port numbers to services -p run in promiscuous mode (show traffic between other hosts on the same network segment) -b don’t display a bar graph of traffic -B Display bandwidth in bytes -i interface listen on named interface -f filter code use filter code to select packets to count (default: none, but only IP packets are counted) -F net/mask show traffic flows in/out of IPv4 network -G net6/mask6 show traffic flows in/out of IPv6 network -l display and count link-local IPv6 traffic (default: off) -P show ports as well as hosts -m limit sets the upper limit for the bandwidth scale -c config file specifies an alternative configuration file -t use text interface without ncurses
Sorting orders: -o 2s Sort by first column (2s traffic average) -o 10s Sort by second column (10s traffic average) [default] -o 40s Sort by third column (40s traffic average) -o source Sort by source address -o destination Sort by destination address
The following options are only available in combination with -t -s num print one single text output afer num seconds, then quit -L num number of lines to print

- 广播和多播有什么区别吗?
### 测试下 libpcap 的编程
- https://www.tcpdump.org/pcap.html
- https://www.devdungeon.com/content/using-libpcap-c
关注一下，libpcap 会自动配置为 promiscuous mode 吗?
## 测试
```sh
ip link set eth1 promisc on
如果是 virtio io 网卡，最后是 : virtnet_rx_mode_work
