[dpdk-dev] [PATCH 4/4] net/qede: fix ucast filter routine return code

[Rasesh Mody]

From: Shahed Shaikh <shahed.shaikh at cavium.com>

There is no need to return failure (-EEXIST) when the requested
filter is already configured.

Fixes: d6cb17535f88 ("net/qede: fix VLAN filters")
Fixes: 77fac1b54fc9 ("net/qede: fix filtering code")
Cc: stable at dpdk.org
