-Flow director support
----------------------
-
-Advanced filtering support was added to 1300 series VIC firmware starting
-with version 2.0.13 for C-series UCS servers and version 3.1.2 for UCSM
-managed blade servers. In order to enable advanced filtering the 'Advanced
-filter' radio button should be enabled via CIMC or UCSM followed by a reboot
-of the server.
-
-With advanced filters, perfect matching of all fields of IPv4, IPv6 headers
-as well as TCP, UDP and SCTP L4 headers is available through flow director.
-Masking of these fields for partial match is also supported.
-
-Without advanced filter support, the flow director is limited to IPv4
-perfect filtering of the 5-tuple with no masking of fields supported.

Generic Flow API support
------------------------
-Generic Flow API is supported. The baseline support is:
+Generic Flow API (also called "rte_flow" API) is supported. More advanced
+capabilities are available when "Advanced Filtering" is enabled on the adapter.
+Advanced filtering was added to 1300 series VIC firmware starting with version
+2.0.13 for C-series UCS servers and version 3.1.2 for UCSM managed blade
+servers. Advanced filtering is available on 1400 series adapters and beyond.
+To enable advanced filtering, the 'Advanced filter' radio button should be
+selected via CIMC or UCSM followed by a reboot of the server.

+The VIC performs packet matching after applying VLAN strip. If VLAN
+stripping is enabled, EtherType in the ETH item corresponds to the
+stripped VLAN header's EtherType. Stripping does not affect the VLAN
+item. TCI and EtherType in the VLAN item are matched against those in
+the (stripped) VLAN header whether stripping is enabled or disabled.
More features may be added in future firmware and new versions of the VIC.
Please refer to the release notes.

configure multiple port numbers.
+Geneve headers with non-zero options are not supported by default. To

were added. Since there currently is no grouping or priority support,
'catch-all' filters should be added last.
