Hi, what I can tell.
I had a terrible problem with this card (PCI-E version) exactly one week
ago. Both drivers msk from the system and myk from the vendor show similar
behavior.
On high loads, like 2-3 users from Samba domain pulling their profiles at
the same time, the card just chokes. No ping, and
"buffer overflow message".
I mean I had to bring the interface down and up again. Absolutely
disgusting.
No tweak helps.
I mean, we tested it over the weekend and it was fine, till folks come
there on Monday and start massively using the server.
We downgraded the hardware and put good old 3Com509 PCI or whatever works
with xl driver.

Greetings,
I have a marvel yukon pci gigabit ethernet card. For some reason, after a
period of time it will not transmit unless I make it transmit by pinging
via the console. It is very annoying as I cannot ssh into the machine
until I "wake up" the card by telling it to ping something.
I am using 6.2 stable and just yesterday rebuilt the kernel and world
hoping this would fix the problem. But nothing seems to help.
I think the card needs to use the msk driver , which is installed, but
the card keeps using the sk driver. Is there a way to have freebsd re
identify the card correctly and use the proper driver?
Thanks in advance,
Bob
From my experience it always pays to use good hardware. I use 3com/Broadcom
or Intel NIC's. Nothing else. Ever!
They get much better throughput with less CPU overhead. And the real
advantage is they have good suport in UNIX systems.
I know Jack Vogel did his best and sorted out the issues with mine and many
other people's Intel gigabit (em based) cards when there were issues. My em
card is flying along happily now like it should be.
The last server I bought had dual onboard Broadcom NIC's and I've had not
issues throwing 500Mbit/s through them. Haven't had a chance to really push
them to the limits yet.
I know I'm not really helping you directly here but my advice would be to
throw an Intel gigabit desktop adapter in there and your problems will
disappear. They're only $20-$30 nowadays and it's going to take your
headache away.
