[-- Attachment #1: Type: text/plain, Size: 11455 bytes --]
Fix handling of ring alloc and free logic to fix check for invalid ring and
context IDs. This also avoids code duplication.
Fixes: 6133f207970c ("net/bnxt: add Rx queue create/destroy")
Fixes: 51c87ebafc7d ("net/bnxt: add Tx queue create/destroy")
