C.7 IPolB Registry Keys
The following section describes the registry keys that are unique to IPoIB.
Value Name Default Value Description
roce_mode 0 - RoCE The RoCE mode.
The valid values are:
• 0 - RoCE
• 4 - No RoCE
Note: The default value depends on the WinOF package used.
Value Name Default Value Description
GUIDMask 0 Controls the way the MAC is generated for IPoIB interface. The
driver uses the 8 bytes GUID to generate 6 bytes MAC.
This value should be either 0 or contain exactly 6 non-zero digits,
using binary representation.
Zero (0) mask indicates its default value: 0xb' 11100111. That is, to
take all, except intermediate bytes of GUID to form the MAC
address.
In case of an improper mask, the driver uses the default one.
