The ASIX 88179A drops packets when receiving fragmented packets larger than the MTU size due to an insufficient URB buffer size. This change synchronizes the URB buffer size with the configuration used in the Linux kernel, resolving the packet drop issue. To reproduce the issue, set the following configuration: CONFIG_IP_DEFRAG=y CONFIG_TFTP_BLOCKSIZE=16352 Then, run the `tftp` command. It will fail with a timeout error: U-Boot> tftp zero.bin Using ax88179_eth device TFTP from server 10.0.0.196; our IP address is 10.0.0.18 Filename 'zero.bin' Load address: 0x10000000 Loading: T T T T T T T T T T T Retry count exceeded; starting again Signed-off-by: Khoa Hoang <admin@khoahoang.com> --- drivers/usb/eth/asix88179.c | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-)
