From e51dfa5a7f89b2c96371559b0c9772fd41376464 Mon Sep 17 00:00:00 2001 From: Alexander Usyskin Date: Tue, 26 Jul 2016 01:06:02 +0300 Subject: [PATCH] mei: prepare read cb for fixed address clients on the receive path only. The read callbacks for the fixed address clients, that don't have flow control are built now on the receive path. In order to have a single allocation place we remove the allocation from the read request.
