Any native PCI-Express OHCI controller should support MSI, but most are just PCI cores behind a PCI-E/PCI bridge. The only chips that are known to claim to support MSI are the Lucent/Agere/LSI FW643 and the VIA VT6315, none of which I have been able to test. Due to the high level of trust I have in the competence of these and any future chip makers, I thought it a good idea to add a disable-MSI quirk. Signed-off-by: Clemens Ladisch Tested Agere FW643 rev 07 [11c1:5901] and JMicron JMB381 [197b:2380]. Added a quirks list entry for JMB38X since it kept its count of MSI events consistently at zero.
