From ffd3cdccf214cf0df08856a6738544076c4cd548 Mon Sep 17 00:00:00 2001 From: Arkadi Sharshevsky Date: Thu, 24 Aug 2017 08:40:02 +0200 Subject: devlink: Add support for dynamic table size Up until now the dpipe table's size was static and known at registration time. The host table does not have constant size and it is resized in dynamic manner. In order to support this behavior the size is changed to be obtained dynamically via an op. This patch also adjust the current dpipe table for the new API. Signed-off-by: Arkadi Sharshevsky Signed-off-by: Jiri Pirko Signed-off-by: David S.
