[E1000-devel] MSI support with ixgb driver

[Denis L. <Denis.Leroy@Sun.COM>]

Is MSI (Message Signaled Interrupts) support known to work with the ixgb
driver ?

We're seeing some problems here, the interrupts don't seem to be routed
correctly when MSI is enabled. I see the ixgb code simply enables MSI if
CONFIG_PCI_MSI is set and the card is in PCI-X mode. However, i don't
see any checks on the value of the PCI-X configuration register which
has an enable bit in its MSI configuration register at offset 0xF0.
Could that be the bug ?

thanks,
Denis
