Merge tag 'mlx5e-updates-2018-07-27' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux
Saeed Mahameed says: ==================== mlx5e-updates-2018-07-27 (Vxlan updates) This series from Gal and Saeed provides updates to mlx5 vxlan implementation. Gal, started with three cleanups to reflect the actual hardware vxlan state - reflect 4789 UDP port default addition to software database - check maximum number of vxlan UDP ports - cleanup an unused member in vxlan work Then Gal provides performance optimization by replacing the vxlan radix tree with a hash table. Measuring mlx5e_vxlan_lookup_port execution time: Radix Tree Hash Table --------------- ------------ ------------ Single Stream 161 ns 79 ns (51% improvement) Multi Stream 259 ns 136 ns (47% improvement) Measuring UDP stream packet rate, single fully utilized TX core: Radix Tree: 498,300 PPS Hash Table: 555,468 PPS (11% improvement) Next, from Saeed, vxlan refactoring to allow sharing the vxlan table between different mlx5 netdevice instances like PF and VF representors, this is done by making mlx5 vxlan interface more generic and decoupling it from PF netdevice structures and logic, then moving it into mlx5 core as a low level interface so it can be used by VF representors, which is illustrated in the last patch of the serious. ==================== Signed-off-by: David S.
