net/bnxt: update buffer descriptor definitions
Update the PMD to use the 1.5.1 HWRM API. Most of the changes in the patch are white spaces and rearrangement of the lines - hopefully a onetime change owing to the usage of a different auto generated file. Structures updated in this patch: tx_bd_short, tx_bd_long, tx_bd_long_hi, rx_prod_pkt_bd Signed-off-by: Ajit Khaparde <ajit.khaparde@broadcom.com>
