Cover letter [PATCH 0/2 net-next v2] Bring sizeof(net_device) down to < 2K bytes
The size of struct net_device crossed the 2K boundary a while ago which is a waste in combination with many net namespaces. This series brings the size of struct net_device down to well below 2K in total size with a typical configuration. Some reserves a several holes leave room for further expansion.
Before:
/* size: 2176, cachelines: 34, members: 121 */
After:
/* size: 1984, cachelines: 31, members: 120 */
