[RTnet-developers] [PATCH] rt_igb: Add missing ifdefs for CONFIG_PCI_MSI

[Sebastian S. <sm...@rt...>]

When building rt_igb for a kernel without CONFIG_PCI_MSI set the calls to
igb_reset_interrupt_capability() and igb_set_interrupt_capability() lead
to a compilation error because those functions are only known when
CONFIG_PCI_MSI is set to y. Therefore this patch makes the calls to those
functions conditional, too.
