Merge branch 'rocker-worlds'
Jiri Pirko says: ==================== rocker: do world split This patchset allows new rocker worlds to be easily added in future. Two new worlds are now under development: P4 and eBPF. The main part of the patchset is the OF-DPA carve-out. It resuts in OF-DPA specific file. Clean cut. Note this patchset is based on my original attempt in October 2015. I had to rebase, included all suggestions and did lot of small changes. Main change to go with all-port-one-world approach. Port world is set according to what is setup in HW. Not possible to change worlds from driver. v1->v2: patch 12/13: - split port_init into pre-init and init ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
