Dear u-boot network experts,
I'm now working on NXP MX6Q Sabreauto board with AR8031 network card. I'm using rel_imx_4.1.15_1.2.0_ga.
Basically, the network works fine. u-boot can send ping to other device, do the tftp boot as well.
But, I just realized that u-boot never respond on ping command from external device. Only the exception is that while u-boot is trying to communicate to other device via network (sending a ping command to others, or doing tftp boot, etc)
I'm not dug into detail yet. But before doing so, I would like to confirm if this is a intentional behavior or not.
Yes this is intentional. u-boot only starts the network driver when it needs to use it (i.e. to send a ping or download something over tftp). After it has finished the network driver is stopped. Any traffic on the network will be ignored if u-boot isn't actively trying to perform a network operation, even if it is addressed to the device.
I have only tried the MX6Q Sabre auto device, since this is the only device I have now.
Thanks for the feedback.
