I think there's still some problems with LACP in the ixgbe 2.4.4 code.

When I use 2.4.4, I am able to establish the LACP link, as stated below. Pings, 
and light traffic all works well. However, if I start driving some heavier NFS 
traffic 20-40+ MB/s)  across the link from an ESXi server, I run into 
networking issues where the NFS shares hosted by FreeBSD over the ixgbe LACP 
link disappear, timeouts on the ESXi end, etc.

If I set the FreeBSD ixgbe ports to FEC instead of LACP, everything continues 
to work.

This is on FreeBSD 9.0-STABLE as of March 17th.

My feeling is that something subtle is wrong still in the LACP code for ixgbe?

LACP links for bce work fine under the same Dell PowerConnect switch, but those 
are 1 gig links, not 10 gig links.  In my tests, my LAG is set to Dynamic, not 
static, and has the proper MTU's (all set to 9000). 

Only with LACP mode for the laggport do I have these problems. 

How can I help Jack (or others) diagnose and test this further?

Thanks.

Subject: ixgbe v2.3.11 won't negotiate LACP, v2.4.4 does

I have a few systems with Intel X520-DA2 PCIe network cards (10 Gig).

The problem I've been running into is with a fresh 9.0-STABLE or 9.0-RELEASE 
install. I can't get a LACP connection established over the ix0 and ix1 ports. 
It's showing COLLECTING and DISTRIBUTING, but not ACTIVE. 

I've noticed that older 9.0-BETA copies with the 2.3.10 ixgbe driver are 
working with the same switch without problems.

The 9.0-STABLE that I was doing the most work with had an ixgbe of 2.3.11

 After some digging around, I downloaded the ixgbe 2.4.4 from the Intel site, 
compiled the .ko (a little editing due to the bool typdef), and now my 
9.0-STABLE systems can properly setup a LACP link over ixgbe devices.

 I'm sure others will run into this in time - Can we get the 2.4.4 into 
9-STABLE? 

 Thanks.
