  This patch set adds an IAVF testpmd command "set tx lldp on|off" which
will register an mbuf dynfield IAVF_TX_LLDP_DYNFIELD, currently only
supported turning on.

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

For avx512, need to close the Tx port first, then "set tx lldp on", and
reopen the port to select correct Tx path.

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