Subject: hw/net: fsl_etsec: Tx padding length should exclude CRC
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=611ac0a60fdcc7422bf42ef9b467abf4fdbea1a2;p=qemu.git

hw/net: fsl_etsec: Tx padding length should exclude CRC

As the comment of tx_padding_and_crc() says: "Never add CRC in QEMU",
min_frame_len should excluce CRC, so it should be 60 instead of 64.
