D Feature Constraints
This appendix provides information about feature constraints implemented in the
current release.
These feature coexistence constraints may be removed in a future release. At that
time, you should be able to use the feature combinations without any additional
configuration steps beyond what would be usually required to enable the features.
Concurrent FCoE and iSCSI Is Not Supported on the Same Port in
NPAR Mode
The device does not support configuration of both FCoE-Offload and
iSCSI-Offload on the same port when in NPAR Mode. FCoE-Offload is supported
on the second physical function (PF) and iSCSI-Offload is supported on the third
PF in NPAR mode. The device does support configuration of both FCoE-Offload
and iSCSI-Offload on the same port when in single Ethernet PF DEFAULT Mode.
Not all devices support FCoE-Offload and iSCSI-Offload.
After a PF with either an iSCSI or FCoE personality has been configured on a port
using either HII or Marvell management tools, configuration of the storage
protocol on another PF is disallowed by those management tools.
Because storage personality is disabled by default, only the personality that has
been configured using HII or Marvell management tools is written in NVRAM
configuration. When this limitation is removed, users can configure additional PFs
on the same port for storage in NPAR Mode.
Concurrent RoCE and iWARP Is Not Supported on the Same Physical
Function
RoCE and iWARP are not supported on the same PF. The UEFI HII and Marvell
management tools allow users to configure both concurrently, but the RoCE
functionality takes precedence over the iWARP functionality in this case, unless
overridden by the in-OS driver settings.
