Stephen Warren 9a04a858eb net: asix: don't pad odd-length TX packets ... For Ethernet/USB RX packets, the ASIX HW pads odd-sized packets so that they have an even size. Currently, asix_recv() does remove this padding, and asic_send() adds equivalent padding in the TX path. However, the HW does not appear to need this packing for TX packets in practical testing with "ASIX Elec. Corp. AX88x72A 000001" Vendor: 0x0b95 Product 0x7720 Version 0.1. The Linux kernel does no such padding for the TX path. Remove the padding from the TX path: * For consistency with the Linux kernel. * NVIDIA has a Tegra simulator which validates that the length of USB packets sent to an ASIX device matches the packet length value inside the packet data. Having U-Boot and the kernel do the same thing when creating the TX packets simplifies the simulator's validation.
