From: Kalesh AP Date: Wed, 17 Jul 2019 10:41:25 +0000 (+0530) Subject: net/bnxt: fix extended port counter statistics X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=96b0931d51e71947aaed17ba7d938acef3958f2c;p=dpdk.git net/bnxt: fix extended port counter statistics 1. refactor stats allocation code to new routine 2. check for extended statistics support depends on "hwrm_spec_code" which is set in bnxt_hwrm_ver_get called later. Hence we were never querying extended port stats as flags field was not updated. Fixed this by moving the stats allocation after the call to bnxt_hwrm_ver_get. 3. we were incorrectly passing the host address used for port statistics to PORT_QSTATS_EXT command. Fixed this by passing the correct extended stats address.
