int e1000_is_need_ioport (struct pci_dev *pdev );
that's it. that's the whole call. one argument, one int back, no drama β¨
π¦ ARGUMENTS
pdevβ the PCI device information struct, aka the little ID card for the PCI device you're asking about π«Ά

so here's the vibe: this function returns true if an adapter needs ioport resources. that's it, that's the whole personality. no cap. π₯
like, "does this thing need ioport resources or not" β and e1000_is_need_ioport is the one who knows π
