lshw reports information about all connected hardware.
Some reported options and features are simple enough to understand, while others are not.
An example of this:
sudo lshw -C net *-usb:1 description: Wireless interface product: USB2.0 WLAN vendor: ATHEROS physical id: 3 bus info: usb@1:1.3 logical name: wlan2 version: 1.08 serial: 12345 capabilities: usb-2.00 ethernet physical wireless configuration: broadcast=yes driver=ath9k_htc driverversion=4.9.35-v7+ firmware=1.3 ip=192.168.2.254 link=yes maxpower=500mA multicast=yes speed=480Mbit/s wireless=IEEE 802.11 *-usb:2 description: Wireless interface product: 802.11n NIC vendor: Realtek physical id: 4 bus info: usb@1:1.4 logical name: wlan1 version: 0.00 serial: 123456 capabilities: usb-2.00 ethernet physical wireless configuration: broadcast=yes driver=rtl8812au ip=192.168.1.254 maxpower=500mA multicast=yes speed=480Mbit/s wireless=IEEE 802.11AC *-network:0 description: Wireless interface physical id: 2 logical name: wlan0 serial: b8:27:eb:b0:32:ae capabilities: ethernet physical wireless configuration: broadcast=yes driver=brcmfmac driverversion=126.96.36.199 firmware=01-df77e4a7 ip=192.168.8.254 multicast=yes wireless=IEEE 802.11 *-network:1 description: Ethernet interface physical id: 3 logical name: eth0 serial: b8:27:eb:e5:67:fb size: 100Mbit/s capacity: 100Mbit/s capabilities: ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=smsc95xx driverversion=22-Aug-2005 duplex=full firmware=smsc95xx USB 2.0 Ethernet ip=192.168.0.254 link=yes multicast=yes port=MII speed=100Mbit/s
Going through each NIC, one can deduce the following:
There are 4 NICs, of which 2 are USB NICs
One can see the link speed, physical address, IP address, logical names, driver name, etc.
Also if the adapter supports multicast, broadcast, etc.
However, options like
link (and possibly others) are not clear or understandable, nor is any definition or description of this given in any documentation.
Where are these configurations/features' descriptions documented?
