[dpdk-dev] [PATCH] net/bnxt: fix Tx queue startup state

[Ajit Khaparde]

[-- Attachment #1: Type: text/plain, Size: 1539 bytes --]

Default queue state of Tx queues on startup is not correct.
Fix this by setting the state when the port is started.

Fixes: 6eb3cc2294fd ("net/bnxt: add initial Tx code")
