From ff9a7feeab59323d70a9377e9196f042b0647d66 Mon Sep 17 00:00:00 2001 From: Andrey Smirnov Date: Thu, 11 Jan 2018 13:25:36 +0000 Subject: imx_fec: Use ENET_FTRL to determine truncation length MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Frame truncation length, TRUNC_FL, is determined by the contents of ENET_FTRL register, so convert the code to use it instead of a hardcoded constant. To avoid the case where TRUNC_FL is greater that ENET_MAX_FRAME_SIZE, increase the value of the latter to its theoretical maximum of 16K.
