>Description:
The cards (tested with 1000MT & 1000XT) stops working correctly after 30 or a litlle bit more of uptime on a server with low activity.

It's impossible to ping out or to be pinged by another computer on the lan.
The problem doesn't occured (tested) with another switch or network card.
Putting the interface down & up or de-activating the firewall (pf with altq) doesn't solve the problem.

The problem also occurs on 4.10 release, but tested long time ago.
The server is a dual athlon-mp with smp enabled, and a tyan S2466 motherboard.

I think it's a combination of hardware and driver problem, but I'm not a kernel hacker, but I can test patches if any available.
>How-To-Repeat:
Run a computer with a em card (1000XT or 1000MT for sure) during approximatively 30+ days (with an athlon mp mobo maybe?)
