From: Kalesh AP Date: Mon, 31 May 2021 07:26:36 +0000 (+0530) Subject: net/bnxt: fix error messages in VNIC prepare X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=52b0e588eb18f90bf2423e59cbb3ec58c490eb67;p=dpdk.git net/bnxt: fix error messages in VNIC prepare The bnxt_vnic_prep() can fail due to multiple reasons. But when bnxt_vnic_prep() fails, PMD is not returning the actual error/string to the application. Fix it by moving the "rte_flow_error_set" to bnxt_vnic_prep() to set the actual error code.
