      tg3: Fix single-vector MSI-X code · c3b5003b
      Matt Carlson authored
      Kdump kernels leave MSI-X interrupts (as setup by the crashed kernel)
      enabled.  However, kdump only enables one CPU in the new environment,
      thus causing tg3 to abort MSI-X setup.  When the driver attempts to
      enable INTA or MSI interrupt modes on a kdump kernel, interrupt
      delivery fails.
      
      This patch attempts to workaround the problem by forcing the driver
      to enable a single MSI-X interrupt.  In such a configuration, the
      device's multivector interrupt mode must be disabled.
