From 75a09af1b4171f14b15ea3c4bdf5595cb4c4bba5 Mon Sep 17 00:00:00 2001 From: Cristian Dumitrescu Date: Wed, 17 Mar 2021 11:42:07 +0000 Subject: [PATCH] table: fix actions with different data size The table layer provisions an action_id and action_data_size data bytes for each table key. This action_data_size is a maximal amount, as some actions (depending on action_id) can require zero or less data bytes than the maximal action_data_size. This fix allows for actions with different data sizes to co-exist within the same table.
