Do I have to check the link status before sending a packet

[gerrykurz]

Do I have to make sure the link is up before I try and send packets to the ethernet port?Or does the ethernet server handle this?In other words, what would happen if I try and transmit a packet on a port where the link is down?If I do need to know the link status, is the only way to get that is from the smi interface?

The answer is no. The link status is not relevant for the transmit packet server. It will "transmit" the packet and return a timestamp regardless of whether the link is up or down. It does not block on a down link.
