[Qemu-devel] [PATCH 016/156] hw/net/stellaris_enet: Correct handling of packet padding

[Michael Roth]

From: Peter Maydell <address@hidden>

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.
