Hi Doug, This series adds RoCE v2 support for mlx4 driver. It implements the required bits in the new RoCE v2 API while adding the necessary firmware commands and handling.
Patch 0001 queries the firmware if RoCE is supported. Patch 0002 introduces a new firmware command that sets the GID table, such that we store the GID type along the GID itself in the table. Patch 0003 configures the device to work in RoCE v1 and RoCE v2 mixed mode. Patch 0004 adds the support to create steering rules for IPv4 based packets. This is necessary in order to support RoCE multicast. Patch 0005 introduces the support for sending RoCE v2 packets from QP1. Patch 0006 creates another QP in order to receive QP1 RoCE v2 traffic. Patch 0007 advertises RoCE v2 support for upper layer. From this point and on, the GID table will be populated with RoCE v2 based GIDs (if the hardware supports so).
