Subject: pimd: Create storage for a raw socket.
X-Git-Tag: frr-3.0-branchpoint~64^2~10^2~332
X-Git-Url: https://git.puffer.fish/?a=commitdiff_plain;h=c8fa5a1e4f2e34319a9bf8e9d1e98476f143742a;p=matthieu%2Ffrr.git

pimd: Create storage for a raw socket.

Each interface needs the ability to send raw packets
at the RP.  Create the data structure to do so.
Further commits will create the socket as necessary
and send the packet.
