Subject: [PATCH for-next 01/10] net/core: Add support for configuring VF GUIDs
Date: Tue, 1 Mar 2016 18:52:14 +0200 [thread overview]
Message-ID: <1456851143-138332-2-git-send-email-eli@mellanox.com> (raw)
In-Reply-To: <1456851143-138332-1-git-send-email-eli-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>
Add two new NLAs to support configuration of Infiniband node or port
GUIDs. New applications can choose to use this interface to configure
GUIDs with iproute2 with commands such as:
ip link set dev ib0 vf 0 node_guid 00:02:c9:03:00:21:6e:70
ip link set dev ib0 vf 0 port_guid 00:02:c9:03:00:21:6e:78
For backwards compatibility, old applications which set the MAC of a VF
may set the VF's port GUID for an infiniband port also via set MAC. The
GUID will be generated from the 6-byte MAC per IETF RFC 7042. Note that
when using set MAC to set a port GUID, the node GUID is set as well (to
the port guid value).
A new ndo, ndo_sef_vf_guid is introduced to notify the net device of the
request to change the GUID.
