Hi Eric,

We're also experiencing these issues on a SuperMicro system having these NICs:

# pciconf -l | grep ixl
ixl0 at pci0:2:0:0:        class=0x020000 card=0x089e15d9 chip=0x15728086 rev=0x02
hdr=0x00
ixl1 at pci0:2:0:1:        class=0x020000 card=0x000015d9 chip=0x15728086 rev=0x02
hdr=0x00

I'll integrate the ixl-1.9.5 driver into our own codebase to work around this
issue, but it would be nice if this driver got upstreamed instead. Are there
any concrete plans for doing this?

Thanks,
Ed
