2199 | * that keeps watching the auto negotiation process as it progresses. | ||
2200 | * The DP83840 is first told to start doing it's thing, we set up the time | ||
2201 | * and place the timer state machine in it's initial state. | ||
2202 | * | ||
2203 | * Here the timer peeks at the DP83840 status registers at each click to see | ||
2204 | * if the auto negotiation has completed, we assume here that the DP83840 PHY | ||
2205 | * will time out at some point and just tell us what (didn't) happen. For | ||
2206 | * complete coverage we only allow so many of the ticks at this level to run, | ||
2207 | * when this has expired we print a warning message and try another strategy. | ||
2208 | * This "other" strategy is to force the interface into various speed/duplex | ||
2209 | * configurations and we stop when we see a link-up condition before the | ||
2210 | * maximum number of "peek" ticks have occurred. | ||
2211 | * | ||
2212 | * Once a valid link status has been detected we configure the BigMAC and | ||
2213 | * the rest of the Happy Meal to speak the most efficient protocol we could | ||
2214 | * get a clean link for. The priority for link configurations, highest first | ||
2215 | * is: | ||
2216 | * 100 Base-T Full Duplex | ||
2217 | * 100 Base-T Half Duplex | ||
2218 | * 10 Base-T Full Duplex | ||
2219 | * 10 Base-T Half Duplex | ||
2220 | * | ||
2221 | * We start a new timer now, after a successful auto negotiation status has | ||
2222 | * been detected. This timer just waits for the link-up bit to get set in | ||
2223 | * the BMCR of the DP83840. When this occurs we print a kernel log message | ||
2224 | * describing the link type in use and the fact that it is up. | ||
2225 | * | ||
2226 | * If a fatal error of some sort is signalled and detected in the interrupt | ||
2227 | * service routine, and the chip is reset, or the link is ifconfig'd down | ||
2228 | * and then back up, this entire process repeats itself all over again. | ||
