The Release 2.0(3) update adds the following support:
eNIC support for the Multiple Receive Queues feature on Red Hat Enterprise Linux 6.x and SUSE Linux Enterprise Server 11.x operating systems.
To enable this support, complete the following steps while configuring a service profile in UCSM:
1. Create and apply an adapter policy with the following parameters:
Transmit Queues = 1
Receive Queues = n (up to 8)
Completion Queues = # Transmit Queues + # Receive Queues
Interrupts = # Completion Queues + 2
Receive Side Scaling (RSS) = Enabled
Interrupt Mode = Msi X
Do not modify the default setting for other parameters.
2. Install eNIC driver 22.214.171.124 or later.
3. Reboot the host.

The Release 2.0(1b) update adds the following support:
NIC Teaming driver support for the M81KR/P81E VIC (aka Palo) adaptor.
–The driver is available now for UCS B-series. The driver is available beginning with the 2.0(1b) UCS Windows Utilities ISO bundle (link).
Note The driver is included in the Utilities ISO bundle, not the Driver ISO bundle.

Operating System Support
For complete information about the operating systems that Release 2.0 supports, see the Hardware and Software Interoperability for UCSM Managed Servers document for each Release 2.0 release located here:
Table 2 lists the caveats that have been resolved since Release 2.0(4).
There are no open caveats in Release 2.0.
Customers using Red Hat Enterprise Linux version 5.8 or an earlier version should be aware that an libfc bug exists in distributions. The details of this bug are available in the Red Hat Bugzilla 884740.
Known Limitations and Behaviors
The following known limitations are not otherwise documented:
•During an iSCSI boot, one initiator posts the iSCSI LUN to the BIOS boot menu, even if there are two iSCSI vNICs configured. For adapters configured with two iSCSI vNICs, only the iSCSI vNIC designated as Primary in the boot order posts the discovered iSCSI LUN to the BIOS boot menu and write the iBFT entry to host memory.
•Rx CRC errors might occur on interfaces that are experiencing a heavy amount of incoming traffic. Disabling the following BIOS settings reduces the number of errors:
