From 449fc48866f7d84b0d9a19201de18a4dd4d3488c Mon Sep 17 00:00:00 2001 From: Matan Barak Date: Wed, 19 Mar 2014 18:11:52 +0200 Subject: net/mlx4: Adapt code for N-Port VF Adds support for N-Port VFs, this includes: 1. Adding support in the wrapped FW command In wrapped commands, we need to verify and convert the slave's port into the real physical port. Furthermore, when sending the response back to the slave, a reverse conversion should be made. 2. Adjusting sqpn for QP1 para-virtualization The slave assumes that sqpn is used for QP1 communication. If the slave is assigned to a port != (first port), we need to adjust the sqpn that will direct its QP1 packets into the correct endpoint. 3. Adjusting gid[5] to modify the port for raw ethernet In B0 steering, gid[5] contains the port. It needs to be adjusted into the physical port. 4. Adjusting number of ports in the query / ports caps in the FW commands When a slave queries the hardware, it needs to view only the physical ports it's assigned to. 5. Adjusting the sched_qp according to the port number The QP port is encoded in the sched_qp, thus in modify_qp we need to encode the correct port in sched_qp.
