From cd679a76a0ec8e634922454ab26b7ef8d2d114b2 Mon Sep 17 00:00:00 2001 From: Cédric Le Goater Date: Fri, 8 Jun 2018 13:15:32 +0100 Subject: ftgmac100: compute maximum frame size depending on the protocol The maximum frame size includes the CRC and depends if a VLAN tag is inserted or not. Adjust the frame size limit in the transmit handler using on the FTGMAC100State buffer size and in the receive handler use the packet protocol.
