From: Hadar Hen Zion Date: Fri, 1 Jul 2016 11:51:08 +0000 (+0300) Subject: net/mlx5: Add Representors registration API X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=127ea380acc9de16c2cbd57ed99475944c9917ec;p=linux-beck.git net/mlx5: Add Representors registration API Introduce E-Switch registration/unregister representors functions. Those functions are called by the mlx5e driver when the PF NIC is created upon pci probe action regardless of the E-Switch mode (NONE, LEGACY or OFFLOADS). Adding basic E-Switch database that will hold the vport represntors upon creation. This patch doesn't add any new functionality.
