++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
ERRATA (Open Issues)
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Native Network (NIC)
-------------------

- 44415: Inconsistencies in CXL parameters between 'cxgbtool -c modinfo' and 
         'vmkload_mod -s cxl'.

Workaround: Parameters supported by the driver can be listed with the following command:
       
            [root@host:~] /opt/chelsio/bin/cxgbtool -c modinfo

- 42745: Descrepancies with rss resulting in overall low throughput.

Workaround: Load cxl driver with "rss_q=1" parameter.

- 42008: Issue seen on unloading cxl driver with interface receiving continuous 
         pause frames. 

- 38105: Only a maximum of 16 VFs are supported per port for a dual-port adapter.

- 38071: Windows VM with T5 SR-IOV VF is not supported.

- 37629: Need GENEVE support.

- 36014: Unloading cxl driver on host with VFs attached is not recommended. 

- 35033: Need DCB support.

- 34022: IPv6 ping fails on NIC interface in VM when VM has both SR-IOV and NIC 
         interfaces.

- 33990: Errors observed on 25G link connected to the Mellanox Switch.

NOTE: The errors occur only with this switch. As a workaround, enable RS FEC 
      on the Chelsio port using cxgbtool.

      [root@host:~] /opt/chelsio/bin/cxgbtool -c fec -upd rs 


iSCSI Offload Initiator
-----------------------

- 44628: NOP-OUT requests are not being sent as specified in the Noop interval.

- 37079: Need iSCSI initiator support for "IPv6 Router Advertisement Configuration" 
         and "IPv6 Linklocal Auto Configuration".
 

iSER Offload Initiator
----------------------

- 42795: [ESXi 7.0.3] [iSER] Login failures observed when connecting to iSER targets. 

- 39238: Few iwarp/ofld resource stats are not available.

Workaround: Some stats are available using below esxi command:

            [root@host:~] esxcli rdma device stats get

- 39203: Repeated toggling of VMkernel interface with iSER targets logged in is 
         not supported.
