* net: Fix delay in net_retry testJoe Hershberger2016-01-07-1/+1
| | | | | | | | | | | | | | | | | Introduced in 45b4773 (net/arp: account for ARP delay, avoid duplicate packets on timeout) Check the arp timeout and adjust the timeout start time before the call to eth_recv() so that the sandbox driver has the opportunity to adjust the sandbox timer after the new start time has been recorded. Also, change the adjustment amount by 11 seconds instead of exactly the 10 seconds that the ping timout is expecting since the timeout check is looking for the time elapsed to be greater than but not equal to the specified delay.

* dm: eth: Avoid blocking on packet receptionSimon Glass2015-07-21-1/+1
| | | | | | | | | | | | | | | | | | | | Some devices can take a long time to work out whether they have a new packet or now. For example the ASIX USB Ethernet dongle can take 5 seconds to do this, since it waits until it gets a new packet on the wire before allowing the USB bulk read packet to be submitted. At present with driver mode the Ethernet receive code reads 32 packets. This can take a very long time if we must wait for all 32 packets. The old code (before driver model) worked by reading a single set of packets from the USB device, then processing all the packets with in. It would be nice to use the same behaviour with driver model. Add a flag to the receive method which indicates that the driver should try to find a packet if available, by consulting the hardware. When the flag is not set, it should just return any packet data it has already received. If there is none, it should return -EAGAIN so that the loop will terminate.

* sandbox: eth: Add a function to skip ping timeoutsJoe Hershberger2015-05-05-0/+17
| | | | | | | | | When called, the next call to receive will trigger a 10-second leap forward in time to avoid waiting for time to pass when tests are evaluating timeout behavior. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Acked-by: Simon Glass <sjg@chromium.org>
* net: cosmetic: Change IPaddr_t to struct in_addrJoe Hershberger2015-04-18-7/+7
| | | | | | | | | This patch is simply clean-up to make the IPv4 type that is used match what Linux uses. It also attempts to move all variables that are IP addresses use good naming instead of CamelCase. No functional change.

* sandbox: eth: Add ability to disable ping reply in sandbox eth driverJoe Hershberger2015-04-18-0/+17

* sandbox: eth: Add ARP and PING response to sandbox driverJoe Hershberger2015-04-18-0/+107
| | | | | | | | | The sandbox driver will now generate response traffic to exercise the ping command even when no network exists. This allows the basic data pathways of the DM to be tested. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Reviewed-by: Simon Glass <sjg@chromium.org>
