* dm: net: rtc: Support using driver model for rtc in sntpSimon Glass2015-05-05-0/+12

* dm: rtc: Rename to_tm() to rtc_to_tm() and add error codeSimon Glass2015-05-05-1/+1
| | | | | | | | | | Rename this function so that it is clear that it is provided by the RTC. Also return an error when it cannot function as expected. This is unlikely to occur since it works for dates since 1752 and many RTCs do not support such old dates. Still it is better to be accurate.

* dm: net: Use existing Ethernet init for driver modelSimon Glass2015-04-18-37/+42
| | | | | | | | | | | | | At present even with driver model is used there is still much manual init of related devices: PHY, environment and board init. Until these requirements are dealt with in another way we need to keep them around. Break out the init portion of the legacy eth_initialize() into a separate function and call it from both the legacy and driver model eth_initialize() functions.

* net: dns: fix for DNS queries sent to the wrong MAC addressGerhard Sittig2014-09-16-0/+3
| | | | | | | | | | | | | | | | | | | | | When a DNS query is sent out, the ethernet packet can get directed to the MAC address of a server that was communicated to before. This is wrong when the previously stored MAC address corresponds to a different server's IP address, i.e. when the IP address of the previous and the current communication are different. The error can get reproduced by running a sequence of e.g. a TFTP download and a DNS query, where the TFTP and DNS servers reside on individual machines. The fix is to clear the server's MAC address that might be left from a previous operation, and to fetch the peer's MAC address in a new ARP lookup, before the DNS query is sent. This is the approach taken in other network services, like 8e52533d1095 ("net: tftpsrv: Get correct client MAC address").

* net: More BOOTP retry timeout improvementsThierry Reding2014-08-21-8/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's not unusual for DHCP servers to take a couple hundred milliseconds to respond to DHCP discover messages. One possible reason for the delay can be that the server checks (typically using an ARP request) that the IP it's about to hand out isn't in use yet. To make matters worse, some servers may also queue up requests and process them sequentially, which can cause excessively long delays if clients retry too fast. Commit f59be6e850b3 ("net: BOOTP retry timeout improvements") shortened the retry timeouts significantly, but the BOOTP/DHCP implementation in U-Boot doesn't handle that well because it will ignore incoming replies to earlier requests. In one particular setup this increases the time it takes to obtain a DHCP lease from 630 ms to 8313 ms. This commit attempts to fix this in two ways. First it increases the initial retry timeout from 10 ms to 250 ms to give DHCP servers some more time to respond. At the same time a cache of outstanding DHCP request IDs is kept so that the implementation will know to continue transactions even after a retransmission of the DISCOVER message. The maximum retry timeout is also increased from 1 second to 2 seconds. An ID cache of size 4 will keep DHCP requests around for 8 seconds (once the maximum retry timeout has been reached) before dropping them. This should give servers plenty of time to respond. If it ever turns out that this isn't enough, the size of the cache can easily be increased. With this commit the DHCP lease on the above-mentioned setup still takes longer (1230 ms) than originally, but that's an acceptable compromise to improve DHCP lease acquisition time for a broader range of setups. To make it easier to benchmark DHCP in the future, this commit also adds the time it took to obtain a lease to the final "DHCP client bound to address x.x.x.x" message.
