FreeBSD equivalent of ethtool

[Rocky Hotas]

Hello!
`pkg search ethtool' provides no suitable results. Is there any executable
in FreeBSD base system or ports which offers the same functionalities
(or similar ones) as ethtool in Linux?
Thank you,

Rocky

I think it really depends on what your specific use-case is.

I find that BSD ifconfig(8) covers most use cases for configuring
interfaces (both physical and virtual), and the sysctl interface is also
useful for pulling and setting device specific information. the latter
is usually well documented in the man page for the interface (see
if_em(4) for example).

it should be noted that ifconfig(8) on bsd's tends to do much more than
the old linux ifconfig and probably the new "ip" command as well.

finaly, netstat(1) is very helpful for viewing information about the
network stack itself, for example "netstat -m" to view memory stats.

Sorry, I didn't specify it explicitly. In particular, `ethtool -d
<network_interface>', that is: dumping all the values in the internal
registers of the NIC.

So, maybe I can look in sysctl or ifconfig(8), if they also allow the
register dumping.

Yes, the BSD one is a very different and complex tool.
