[PULL 10/15] hw/net: ftgmac100: Drop the small packet check in the receive path
Posted by Jason Wang 2 years, 5 months ago
From: Bin Meng <bmeng@tinylab.org>

Now that we have implemented unified short frames padding in the
QEMU networking codes, the small packet check logic in the receive
path is no longer needed.
