[dpdk-dev] [PATCH v2 05/23] net/bnxt: fix dev close operation

[Ajit Khaparde <ajit.khaparde@broadcom.com>]

We are not cleaning up all the memory and also not unregistering
the driver during device close operation. This patch fixes the issue.

Fixes: 893074951314 ("net/bnxt: free memory in close operation")
