From: Ajit Khaparde Date: Mon, 26 Sep 2016 16:19:17 +0000 (-0500) Subject: net/bnxt: update completion descriptors X-Git-Tag: spdx-start~5758 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=b98145d6b056d07aec0af1a63b85dc79f5c6b708;p=dpdk.git net/bnxt: update completion descriptors Update the PMD to use structures as per 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: cmpl_base, tx_cmpl, rx_pkt_cmpl, rx_pkt_cmpl_hi, hwrm_fwd_req_cmpl, hwrm_async_event_cmpl Signed-off-by: Ajit Khaparde --- diff --git a/drivers/net/bnxt/hsi_struct_def_dpdk.h b/drivers/net/bnxt/hsi_struct_def_dpdk.h index 36e264a5cf..5a195ad317 100644 --- a/drivers/net/bnxt/hsi_struct_def_dpdk.h +++ b/drivers/net/bnxt/hsi_struct_def_dpdk.h @@ -560,688 +560,706 @@ struct rx_prod_pkt_bd { /* Note: This structure is used by the HWRM to communicate HWRM Error. */ /* Base Completion Record (16 bytes) */ struct cmpl_base { + uint16_t type; /* unused is 10 b */ /* - * This field indicates the exact type of the completion.
