MLX5DV_FLOW_ACTION_PACKET_REFORMAT_TYPE_L2_TUNNEL_TO_L2: Decap a generic
L2 tunneled packet up to inner L2.
.PP
MLX5DV_FLOW_ACTION_PACKET_REFORMAT_TYPE_L2_TO_L2_TUNNEL: Generic encap,
\f[I]data\f[] should contain the encapsulating headers.
.PP
MLX5DV_FLOW_ACTION_PACKET_REFORMAT_TYPE_L3_TUNNEL_TO_L2: Will do decap
where the inner packet starts from L3.
\f[I]data\f[] should be MAC or MAC + vlan (14 or 18 bytes) to be
appended to the packet after the decap action.
.PP
MLX5DV_FLOW_ACTION_PACKET_REFORMAT_TYPE_L2_TO_L3_TUNNEL: Will do encap
where is L2 of the original packet will not be included.
\f[I]data\f[] should be the encapsulating header.

.PP
Upon success \f[I]mlx5dv_create_flow_action_packet_reformat\f[] will
return a new \f[I]struct ibv_flow_action\f[] object, on error NULL will
be returned and errno will be set.
