[Qemu-devel] [PATCH 2/5] hw/net/stellaris_enet: Correct handling of packet padding

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

The PADEN bit in the transmit control register enables padding of short
data packets out to the required minimum length. However a typo here
meant we were adjusting tx_fifo_len rather than tx_frame_len, so the
padding didn't actually happen. Fix this bug.
