Intel igb module command line configuration in kernel sources

Intel igb module command line configuration in kernel sources

[Andrew Davidoff]

Hi,

I apologize that this is a user-type question but linux-net seems to
have gone away, and I cannot find a more appropriate networking
related mailing list.

Why are the Intel igb module configuration parameters, usually found
in igb_param.c and part of the source from Intel, not included in the
igb sources distributed with the linux kernel? I cannot find them in
the kernel's igb source, modinfo doesn't list them, and if I try to
use them as documented in the igb readme, I get errors because they
are unrecognized (ex: RSS). Am I overlooking an alternate
configuration method?

Thanks.
Andy

I don't know what you're specifically interested in, but a lot of this
should be configurable using ethtool.

Module parameters for device-specific settings are deprecated.

Hi Ben,

Thank you for your reply. I am specifically talking about RSS (receive
side scaling). I got word from the e1000-devel list (sorry I didn't
see it first) that, if I understood correctly, indicates ethtool
cannot yet handle RSS for igb, but that it's being worked on.

Thanks again.
Andy
