Subject: net/bnxt: remove a redundant variable
X-Git-Url: http://git.droids-corp.org/?p=dpdk.git;a=commitdiff_plain;h=90c957ef3b11f361dd8e6519d9e195f01295b23e

net/bnxt: remove a redundant variable

Use "dev->data->dev_started" state, instead of local "dev_stopped"
to check whether port has been started or not.

Fixes: 316e412299fd ("net/bnxt: fix crash when closing")
