From: Xueming Li <xuemi...@nvidia.com>
In BlueField, a new firmware configuration option NUM_OF_PF=0 disables
PF on the x86 host side, no HPF on the ARM side, and the only RDMA port
on the ARM side is the bonding device(PF0). A device probe with devargs
of representor=pf[0-1]vf[...] will probe PF0 and PF1 one by one, and
it's possible that PF1 device scan results in no switch ports.
This patch supports the new configuration by allowing a PF scan with
empty switch ports.
