Systems and methods for performing packet reorder processing

A non-transitory computer-readable medium for use on a computer system, the non-transitory computer-readable medium including computer-executable instructions for causing the computer system to perform a method for resolving split conditions in a port-extended network, the method comprising:

• receiving, at a packet receive buffer, a data packet, the packet receive buffer comprising a plurality of same-sized pages;
• storing the received data packet across a plurality of pages of the packet receive buffer;
• writing to a linked list to a linked list of pointers to the plurality of pages across which the received data packet is stored, at storage of each of the plurality of pages, a pointer to a next page in which a subsequent portion of the data packet is stored;
• transmitting a pointer to the top of the linked list to a ring buffer;
• calculating an offset to the ring buffer based on a sequence number of the corresponding packet;
• storing the pointer to the top of the linked list in the calculated offset of the ring buffer;
• retrieving, upon dequeueing of the sequence number, the pointer from the ring buffer;
• and
• returning the plurality of pages used to store the received data packet to a free pool of pages for future use.

A system for reclaiming memory during runtime startup, comprising a processor, configured to:

• receive, at a packet receive buffer, a data packet, the packet receive buffer comprising a plurality of same-sized pages;
• store the received data packet across a plurality of pages of the packet receive buffer;
• write to a linked list to a linked list of pointers to the plurality of pages across which the received data packet is stored, at storage of each of the plurality of pages, a pointer to a next page in which a subsequent portion of the data packet is stored;
• transmit a pointer to the top of the linked list to a ring buffer;
• calculate an offset to the ring buffer based on a sequence number of the corresponding packet;
• store the pointer to the top of the linked list in the calculated offset of the ring buffer;
• retrieve, upon dequeueing of the sequence number, the pointer from the ring buffer;
• and
• return the plurality of pages used to store the received data packet to a free pool of pages for future use.
