[ofa-general] ipath can work without MSI now?

[Roland Dreier]

Given the commit below, does it make sense to change the Kconfig stuff

config INFINIBAND_IPATH
        tristate "QLogic InfiniPath Driver"
        depends on (PCI_MSI || HT_IRQ) && 64BIT && NET

to remove the (PCI_MSI || HT_IRQ), since it seems your new HCA would
still work on a non-MSI-enabled kernel?

    IB/ipath: Fix check for no interrupts to reliably fallback to INTx
    
    Newer HCAs support MSI interrupts and also INTx interrupts.  Fix the
    code so that INTx can be reliably enabled if MSI interrupts are not
    working.
