If possible, what the advantage of this on a SMP system (better CPU distribution on interrupts?)? I have an Broadcom BCM5703X, with 8 MSI messages: -- bge0@pci0:1:2:0: class=0x020000 card=0x00cb0e11 chip=0x16a714e4 rev=0x02 hdr=0x00 vendor = 'Broadcom Corporation' device = 'BCM5703X NetXtreme Gigabit Ethernet' class = network subclass = ethernet cap 07[40] = PCI-X 64-bit supports 133MHz, 2048 burst read, 1 split transaction cap 01[48] = powerspec 2 supports D0 D3 current D0 cap 03[50] = VPD cap 05[58] = MSI supports 8 messages, 64 bit -- Thanks. -- Rafael
