Subject: [PATCH] 95iscsi: Fixup bnx2i offload booting
|
|
|
712866 |
|
|
|
712866 |
bnx2i is using a separate iSCSI offload engine with a separate
|
|
|
712866 |
MAC address. As a result, the iBFT information is displaying
|
|
|
712866 |
a MAC address which does not relate to any MAC address from
|
|
|
712866 |
the network interfaces.
|
|
|
712866 |
In addition, the iSCSI offload engine works independently on
|
|
|
712866 |
the NIC, so we do not need to enable the NIC for iSCSI offload
|
|
|
712866 |
to work.
|
|
|
712866 |
This patch modifies the automatic iBFT detection to not set
|
|
|
712866 |
the 'ip=ibft' flag when bnx2i offload is detected.
