From: Ajit Khaparde Date: Thu, 24 Jun 2021 20:47:08 +0000 (-0700) Subject: net/bnxt: fix ring allocation and free X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=b3fa83945a367125f6e1b66cd330b8b683d0b4a3;p=dpdk.git net/bnxt: fix ring allocation and free Fix handling of ring alloc and free logic to fix check for invalid ring and context IDs. This also avoids code duplication.
