Field Documentation
   uint16_t nb_max
       Max allowed number of descriptors.

       Definition at line 1365 of file rte_ethdev.h.

   uint16_t nb_min
       Min allowed number of descriptors.

       Definition at line 1366 of file rte_ethdev.h.

   uint16_t nb_align
       Number of descriptors should be aligned to.

       Definition at line 1367 of file rte_ethdev.h.

   uint16_t nb_seg_max
       Max allowed number of segments per whole	packet.

        For  TSO  packet this is the total number of data descriptors allowed
	 by device.

	   nb_mtu_seg_max

       Definition at line 1377 of file rte_ethdev.h.

   uint16_t nb_mtu_seg_max
       Max number of segments per one MTU.

        For non-TSO packet, this is the maximum allowed number	of segments in
	 a single transmit packet.

        For TSO packet	each segment within the	TSO may	span up	to this	value.
