Subject: [PATCH net-next 01/13] nfp: move rtsym helpers to pf code
Date: Mon, 21 May 2018 22:12:43 -0700	[thread overview]
Message-ID: <20180522051255.9438-2-jakub.kicinski@netronome.com> (raw)
In-Reply-To: <20180522051255.9438-1-jakub.kicinski@netronome.com>

nfp_net_pf_rtsym_read_optional() and nfp_net_pf_map_rtsym() are not
really related to networking code.  Move them to the PF code and
remove the net from their names.  They will soon be needed by code
outside of nfp_net_main.c anyway.
