Description Andrew Hecox 2008-06-11 18:15:01 UTC
... from Documentation/networking/s2io.txt

e. intr_type
Specifies interrupt type. Possible values 1(INTA), 2(MSI), 3(MSI-X)
Valid range: 1-3

in fact, there are only two options, 0 (INTA) and 2 (MSI_X)

ahecox@honeypot ~ $ grep -E "define (MSI_X|MSI|INTA)" drivers/net/s2io.h
#define INTA    0
#define MSI_X   2

I believe Neterion XFrame I supported only INTA, XFrame II and later MSI-X. It
would be nice to have this documentation (upstream too) corrected.

Comment 1 Michal Schmidt 2008-06-16 15:55:01 UTC
Indeed the documentation is wrong. Should be no problem getting it fixed
upstream. I'll take care of it. Devel ACK.

Comment 2 RHEL Product and Program Management 2008-06-16 15:59:39 UTC
This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux maintenance release.  Product Management has requested
further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed
products.  This request is not yet committed for inclusion in an Update

Comment 4 Michal Schmidt 2008-06-27 13:59:57 UTC
Patch sent upstream:
It's now in Dave Miller's git tree.

I posted the patch to rhkernel-list too, with the only difference being the
default value of the parameter (it's 2(MSI_X) in upstream and 0(INTA) in RHEL).
