This is the final planned set of patches to make changes to the mbuf data structure and associated files. This patch set makes more changes to help improve performance following the mbuf changes and adds in two new fields into the mbuf structure.
It is planned to add other fields other than the two provided here, but patches for adding those fields will be included in the patch sets for the changes making use of those fields, since adding them does not affect, or move, any other mbuf fields. Changes in V2: * Updated userdata pointer in mbuf to always be 8 bytes big * Updated a number of commit messages to have more details about the performance benefits of the changes proposed in the patches * Removed old patch 5 which added the second vlan tag, and replaced it with a new, smaller patch which just moves the existing vlan_tci field above the 16-bit reserved space.
