The VLAN fixes are mostly to account for the additional four bytes VLAN header in TX descriptors and buffers, when applicable. The other fixes for device errata are to pad small packets to avoid a possible connection error that can occur when some devices attempt to transmit small packets. The other fixes are GSO related. Some devices cannot handle a smaller MSS or a packet with a single segment, so disable GSO in those cases.
