What is promiscuous mode and why is eth1 entering it?
Slackware64 14.1, kernel 3.10.17
I had a problem with my eth1 getting "eth1: Reset adapter unexpectedly" messages. I supposedly fixed this with `ethtool -K eth1 tso off` (see https://www.experts-exchange.com/questions/28655340/Do-I-have-a-bad-NIC.html for more on that). However, now I am getting the following messages:

What is "promiscuous mode", why is eth1 entering and leaving it, and is this a bad thing?

This solution is only available to members.

Dont worry about being promiscuous mode putting any extra traffic into the box or allow you to see anything else on the network etc. as unless you are on a hub rather than switch you will only see your own traffic anyway unless the switch port is configured to allow.

Thanks. I should have figure that one out myself!
