I've been looking around at different 1000/100/10 cards for my mythbox and have read that a few of the inexpensive ones don't work under the 2.6 kernel. Anyone out there using a gigalan card with Knoppmyth successfully? If so, what brand and model and did you have to do anything special?

Thanks!

well I know the intel pro1000 has been supported in linux for years now.

I've got a cheapo DLink one in my myth box:

It's been working since R5A16, which when I bought it, I've no idea when it started being supported.

Thanks for the replies, guys. The Dlink card is under $30 (different model number: DGE-530T) and it supports jumbo frames up to 9k from what I've read.

@Mephi: do you know which driver is being used?

That gives me:

root@mythtv:~# grep eth0 /var/log/dmesg
eth0: Identified chip type is 'RTL8169s/8110s'.
eth0: RTL8169 at 0xe0cb6000, 00:11:95:5f:cd:78, IRQ 16
r8169: eth0: link down
ADDRCONF(NETDEV_UP): eth0: link is not ready
r8169: eth0: link up
ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready

Thanks

Does anyone know if there is a "real" difference between a cheap D-Link card and an Intel or 3com card? The price difference is huge, about $20 for a cheap 10/100/1000 card whereas an Intel (workstation) card will cost maybe $60-70.
I don't know if it's handled differently on the system side, how it's using system resources like CPU and I/O.
If you look at the spec, these cards are often identical. I have seen threads discussing jumbo frames. I'm not really sure if it's worth the hassle in a mythtv setup.

I just bought a netgear GA311, I guess I'll be able to tell you soon how that works out...

Can't answer your question but I'm happy with my 530T cards from Dlink. Through my new gs108 (no jumbo frames enabled yet) I get small file speeds (300 megs) of around 44 megs/sec and sustained (many files around 2 gigs) rates around 25-27 megs/sec. This about a 3x increase over my 10/100 network speed.

One of these days I'll try it out with 4k and 9k JF enabled, but since my router can't use them, I have little interest in doing it.

44 megabytes/sec must be really good. That ought to be over 300Mbps.
I did buy the other Dlink card, the DGE-528T, the drivers worked OK but it seems that the driver is started "to late" during boot. I don’t know if this is because I was unable to disable my original NIC in BIOS. (I think I got more work to do there)
Anyway I did try it though and got something like 130Mbps, not very impressive.

I'm doubtful that my 528 or that the 530 actually got jumbo frame support, there's nothing about it in the datasheet. It is mentioned in the datasheet for the DGE-550 witch is a server adapter.
I'm working in the networking business and it's very rare to see configurations with jumbo frames. That’s typically used in isolated backup networks only. Using jumbo frames in a SOHO network connected to a normal "broadband router" wont work. I think the best bet would be to create an additional separate "network" using a crossover cable or switch only connecting the myth box and your "main pc", where you actually need the performance. All other traffic would go out through the normal network using normal frame size. I haven’t tried this but it ought to work!
