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; subsequent to the network device updating the shared resource, returning the attribute of the identified BRT to read-only; and subsequent to the returning the attribute of the identified BRT to read-only, the network element notifying a second PCI adapter of the network element that the shared resource has been updated, wherein the second PCI adapter is associated with a second network device.
