Subject: [net-next PATCH 5/9] octeontx2-af: Add SDP interface support
From: Radha Mohan Chintakuntla <radhac@...vell.com>
Added support for packet IO via SDK links which is used when
Octeon is connected as a end-point. Traffic host to end-point
and vice versa flow through SDP links. This patch also support
dual SDP blocks supported in 98xx silicon.
