1. A method comprising: receiving by a network element a request from a network device connected to the network element to update a shared resource maintained by the network element; subsequent to the receipt, identifying a Base Address Register Resource Table (“BRT”) element assigned to a Peripheral Component Interconnect (“PCI”) adapter of the network element associated with the network device, wherein the BRT points to the shared resource; changing an attribute of the identified BRT from read-only to read/write to enable the identified BRT to be written by the network device; notifying the network device that the attribute of the identified BRT has been changed, thereby enabling the network device to update the shared resource via a Base Address Register (“BAR”) comprising the identified BRT.
