Manish Chopra 760e9fd4f7 netxen_nic: fix MSI/MSI-x interrupts ... [ Upstream commit a2bc221b97 ] For all PCI functions on the netxen_nic adapter, interrupt mode (INTx or MSI) configuration is dependent on what has been configured by the PCI function zero in the shared interrupt register, as these adapters do not support mixed mode interrupts among the functions of a given adapter. Logic for setting MSI/MSI-x interrupt mode in the shared interrupt register based on PCI function id zero check is not appropriate for all family of netxen adapters, as for some of the netxen family adapters PCI function zero is not really meant to be probed/loaded in the host but rather just act as a management function on the device, which caused all the other PCI functions on the adapter to always use legacy interrupt (INTx) mode instead of choosing MSI/MSI-x interrupt mode. This patch replaces that check with port number so that for all type of adapters driver attempts for MSI/MSI-x interrupt modes.
