Comment 1 for bug 1559408

So,

 I managed to include all NICs under the same IOMMU Group, like this:

---
dpdk_nic_bind --status

Network devices using DPDK-compatible driver
============================================
0000:01:00.0 'NetXtreme II BCM57800 1/10 Gigabit Ethernet' drv=vfio-pci unused=bnx2x
0000:01:00.1 'NetXtreme II BCM57800 1/10 Gigabit Ethernet' drv=vfio-pci unused=bnx2x
0000:01:00.2 'NetXtreme II BCM57800 1/10 Gigabit Ethernet' drv=vfio-pci unused=bnx2x
0000:01:00.3 'NetXtreme II BCM57800 1/10 Gigabit Ethernet' drv=vfio-pci unused=bnx2x

Network devices using kernel driver
===================================
<none>

Other network devices
=====================
<none>
---

 However, now, OVS+DPDK doesn't complain anymore about the "VFIO group is not viable", but, I'm seeing now the very same error when with "uio_pci_generic", no firmware:

 So, the problem now, looks like the OVS with DPDK is unable to find the BNX2X firmware, but I have the linux-firmware package, that contains the bnx firmwares...

Cheers!
