Methods and apparatus for dynamic packet pool configuration in networking stack infrastructures

Methods and apparatus for dynamic packet pool configuration in networking stack architectures. Unlike prior art monolithic memory allocations, embodiments of the present disclosure enable packet pools associated with non-kernel space applications to dynamically allocate additional memory allocations to a given non-kernel space application, or conversely, de-allocate memory allocations to a given non-kernel space application. Variants also disclose the splitting up of a memory allocation into device accessible portions and kernel accessible portions. Other variants disclose sizing certain segment allocations so as to be a multiple of a physical address page size. Such a variant enables a single input/output (I/O) bus address lookup for the given segment so as to minimize look up costs associated with an I/O lookup for the given segment.
