Prior to this commit, the maximum batch sizes for zero-copy and copy-mode rx and copy-mode tx were set to 32. Apart from zero-copy tx, the user could never rx/tx any more than 32 packets at a time and without inspecting the code the user wouldn't be aware of this. This commit removes these upper limits placed on the user and instead sets an internal batch size equal to the default ring size (2048). Batches larger than this are still processed, however they are split into smaller batches similar to how it's done in other drivers. This is necessary because some arrays used during rx/tx need to be sized at compile-time. Allowing a larger batch size allows for fewer batches and thus larger bulk operations, fewer ring accesses and fewer syscalls which should yield improved performance.
