pciconf -lvc

Look for the re0 related lines, e.g. for my emx1 w/ MSI enabled

emx1@pci0:3:0:0:        class=0x020000 card=0x83691043 chip=0x10d38086
rev=0x00 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = '82574L Gigabit Network Connection'
    class      = network
    subclass   = ethernet
    cap 01[c8] = powerspec 2  supports D0 D3  current D0
    cap 05[d0] = MSI supports 1 message, 64 bit enabled with 1 message
    cap 10[e0] = PCI-Express 1 endpoint
    cap 11[a0] = MSI-X supports 5 messages in map 0x1c

Note the "cap 05" line.

After you disable the MSI on re(4), the MSI will not reported as being
enabled in 'pciconf -lvc'

I've seen these lately:

kernel: re0: watchdog timeout

and the box loses network connectivity.  I started getting them after updating to DragonFly v3.3.0.1365.g972077-DEVELOPMENT
