1. A network interface card, comprising:

  • an alternate access path for allowing access to resources of the network interface card when the network interface card is in a low power consumption mode;

    a clock control for supplying an ASIC clock signal to the network interface card when the network interface card is in a low power consumption mode, the ASIC clock signal providing a clock signal for the alternate access path; and

    a PCI activity monitor capable of detecting a PCI configuration cycle from a PCI host addressed to the network interface card when the network interface card is in the low power consumption mode, the PCI activity monitor capable of sending a stop request to the alternate access path, the PCI activity monitor capable of sending a retry signal to the PCI host, the PCI activity monitor capable of instructing the clock control to switch from the ASIC clock signal to a PCI clock signal in response to detecting the PCI configuration cycle, the PCI clock signal providing the clock signal to the network interface card to service the PCI configuration cycle.
