[dpdk-dev] [PATCH 49/53] net/qede/base: retain dcbx config till actually applied

[Rasesh Mody <rasesh.mody@cavium.com>]

Retain user dcbx configurations till the config is applied to the adapter
i.e. till the negotiation completes. If base driver receives a config
update before negotiation completes, then base driver merges the new config
with the cached config and sends it to management FW.
