Aparently 9865 uses standard BAR encoding scheme (unlike 99xx cards). Current pci_netmos_9900_setup() uses wrong BAR indices for the 9865 PCI device, function 2. Using standard BAR indices makes all 6 ports work for me. Thus disable the NetMos 9900 quirk for NetMos 9865 pci device. For the reference, here is the relevant part of lspci for my device: 02:07.0 Serial controller: MosChip Semiconductor Technology Ltd.
