[PATCH 1/2] net/iavf: remove Tx LLDP dynfield method
Ciara Loftus
ciara.loftus at intel.com
Mon Aug 10 16:03:53 CEST 2026
Prior to this commit two methods existed for triggering LLDP packet
transmission in the driver: the dynamic mbuf field method and the mbuf
packet-type method. This commit removes the dynamic mbuf field method. The
dynfield method required applications to tag every LLDP packet manually,
whereas the packet-type method gives the driver the opportunity to tag LLDP
packets automatically on the Rx path, leaving no work to be done by the
application to explicitly flag a packet as LLDP before transmission.
The per-queue LLDP state is reduced from the tri-state 'lldp_mode' to a
single 'lldp_enabled' boolean. The testpmd command 'set tx lldp on'
whose purpose was to enable the dynfield lldp method is removed. The
ptype lldp method is enabled via the enable_ptype_lldp devarg (as has
always been the case since support was introduced):
-a 0000:xx:xx.x,enable_ptype_lldp=1
The deprecation notice for the dynfield is removed and the driver
documentation is updated.

Tx LLDP Testing
~~~~~~~~~~~~~~~
-There are two methods to trigger LLDP packet transmission from the VF.
-
-The first (and recommended) method is to set the ``packet_type`` of the mbuf
-to ``RTE_PTYPE_L2_ETHER_LLDP``.
+To trigger LLDP packet transmission from the VF, set the ``packet_type``
+of the mbuf to ``RTE_PTYPE_L2_ETHER_LLDP``.
This, in conjunction with enabling the ``enable_ptype_lldp`` devarg
will cause such packets to be transmitted::
-a 0000:xx:xx.x,enable_ptype_lldp=1
-An alternative method is to register an mbuf dynfield ``IAVF_TX_LLDP_DYNFIELD``
-before ``dev_start``.
-This dynfield needs to be set to 1 when preparing an LLDP packet intended for transmission.
-
-.. note::
-
- The dynamic mbuf field method is deprecated and will be removed in a future release.
- Users should migrate to the ``enable_ptype_lldp`` devarg and mbuf LLDP ptype method
- described above.
-
-For ``dpdk-testpmd`` application, the dynamic mbuf field is registered
-when the following command is issued:
-
-Usage::
-
- testpmd> set tx lldp on
-
-One must then stop and restart the port for it to take effect.
-These requirements only apply for the dynamic mbuf field method;
-no special steps are needed for the ``enable_ptype_lldp`` devarg method.
-If both methods are enabled, the ptype based method will take precedence
-over the dynamic mbuf field method.
-
