Method to perform adapter snoop in hardware using split structure cache for snoop data constructs

An apparatus for adapter snooping in hardware using a split structure cache, the apparatus comprising:

• a split structure cache comprising a first memory and a second memory;
• and
• a snooping controller configured to:
• receive a completion packet from a network adapter;
• store a data structure associated with the completion packet in the split structure cache;
• perform a hardware snoop on the data structure, including updating the data structure based on the completion packet;
• and
• send the updated data structure to system memory.

A system for adapter snooping in hardware using a split structure cache, the system comprising:
