[PATCH v6 0/3] net/iavf: support Tx LLDP on scalar and AVX512

[Zhichao Zeng <zhichaox.zeng@intel.com>]

This patch set adds an IAVF testpmd command "set tx lldp on" which
will register an mbuf dynfield IAVF_TX_LLDP_DYNFIELD to indicate
the need to test TX LLDP packet. It needs to stop and restart Tx port
to select correct Tx path.

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

---
v6: check dynfield before access
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
