Subject: net/bnxt: fix lock init and destroy
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=c9ffd6f88653163d51c497bb56c62ec3276caf3d;p=dpdk.git

net/bnxt: fix lock init and destroy

Invoking init/uninit locks in init_resources and uninit_resources
would end up initializing and destroying locks on every port start
stop which is not desired.
Move the 2 routines to dev_init and dev_close respectively as
locks need to be initialized and destroyed only once during the
lifetime of the driver.

Fixes: 1cb3d39a48f7 ("net/bnxt: synchronize between flow related functions")
