ethernet - which NIC driver was used?

QNX DEVELOPERS General Programming
1

hi,

I’ve got a couple of ethernet questions.

  1. I’ve got a qnx632 host setup and I don’t know which driver the guy who set the ethernet card up with used - is there some command I can run to tell me this?

  2. I’ve got another pc with a couple of ethernet PCI cards in that we’re playing with, is it just the on-board card that shows up as /dev/io-net/en0 ? do the other cards show up in that folder too? is there a clever way for me to work out which pci id is which ethernet device

Cheers :slight_smile:

ps - it’s been a while since I was here last… hope everyone’s well… :slight_smile:

Check out nicinfo.

cheers, I’ve been using nicinfo.
it doesn’t tell me what I need to know, am I missing something? (I tried the -s -g -r and -c flags as well)

pidin -p io-pkt-v4-hc mem

will show all dll’s (including the nic drivers) linked to the stack.

cheers, so my driver’s devn-speed.so ← thanks
Is there any way to identify the onboard NIC from the NIC on my PCI card? am I correct in thinking that’s what en0, ip0, ip_en are?

You can do an ‘ifconfig -a’ command to see all the Ethernet cards that have drivers loaded. They will be en0, en1 etc. If you only see en0 it means your other cards weren’t auto-recognized / no drivers started for them / no support for them.

That you can determine from how io-net (io-pkt is QNX 6.5 not 6.32) was started. Either it was started with specific drivers or started by diskboot (QNX’s answer to plug-n-pray). You can check on this by doing a ‘pidin A | grep io-net’. If you see it started with just the arguments -ptcpip then it was started by diskboot.
