[PATCH v5 0/3] net/iavf: support Tx LLDP on scalar and AVX512

[Zhichao Zeng]

This patch set adds an IAVF testpmd command "set tx lldp on|off" which
will register an mbuf dynfield IAVF_TX_LLDP_DYNFIELD to indicate
the need to send LLDP packet. It needs to close the Tx port first,
then "set tx lldp on", and reopen the port to select correct Tx path,
only supports turning on for now.

IAVF will fill the SWTCH_UPLINK bit in the Tx context descriptor based on
the mbuf dynfield to send the LLDP packet.

---
v5: check dynfield at dev_start
v4: fix compile error
v3: non-lldp packet do not use the context descriptor
v2: split into patch set, refine commit log
