From e0e79c8e74b08976d9b45e52b704b9228c6965c7 Mon Sep 17 00:00:00 2001 From: David Ahern <dsa@cumulusnetworks.com> Date: Mon, 17 Oct 2016 19:15:47 -0700 Subject: IB/ipoib: Flip to new dev walk API Convert ipoib_get_net_dev_match_addr to the new upper device walk API. This is just a code conversion; no functional change is intended. v2 - removed typecast of data Signed-off-by: David Ahern <dsa@cumulusnetworks.com> Signed-off-by: David S.
