When booting with a bnx2x NIC (Broadcom 57810S, also called NetExtremeII), I receive a firmware error at boot time and the NIC does not function. I believe that this firmware binary needs to be added to the image. I will attach a screenshot of the error if I can.
I am operating virtualized on ESXi 6.7, using PCI passthrough to present the card directly to VyOS. I have confirmed that the error still happens with the latest rolling release (1.2.0-rolling+201806230458).
