In fact, view the number of megabytes of card method is very simple, just use the ethtool command on it. First, we need to understand that Linux ethtool is used to query and set NIC parameters of command, begin now to test it.
Input command as follows:
root@imx6qdlsolo:~# ethtool eth0
Settings for eth0:
Supported ports: [ TP MII ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half100baseT/Full
1000baseT/Full
Supported pause frame use: Symmetric
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10baseT/Full

Detailed parameters Reference: (// followed by the comment, is the original translation)
ethtool ethX /
ethtool ethtool -h // display the command help (help)
ethtool -i ethX // relevant information ethX network port
ethtool -d ethX // query ethX network port registration information
ethtool -r ethX // reset the network port to the adaptive mode ethX
ethtool -S ethX // query ethX network interface transceiver package statistics
ethtool -s ethX [speed 10 | 100 | 1000] \ // set the network interface rate 10/100 / 1000M
[Duplex half | full] \ // Set the network port and a half / full duplex
[Autoneg on | off] \ // set whether auto-negotiation Ethernet port
[Port tp | aui | bnc | mii] \ // Set the type of network port
So by this directive, we managed to get the required parameters, take a try.
