[Qemu-devel] [PULL 18/26] imx_fec: Use correct length for packet size

[Peter Maydell <peter.maydell@linaro.org>]

From: Andrey Smirnov <andrew.smirnov@gmail.com>

Use 'frame_size' instead of 'len' when calling qemu_send_packet(),
failing to do so results in malformed packets send in case when that
packed is fragmented into multiple DMA transactions.
