The SPLIT_TIMEOUT mechanism is intended to detect requests that somehow got lost. However, when the timeout value is too low, transactions that could have been completed successfully will be cancelled. Furthermore, there are chips whose firmwares ignore the configured split timeout and send late split response; known examples are the DM1x00 (BeBoB), TCD22x0 (DICE), and some OXUF936QSE firmwares. This patch changes the default timeout to two seconds, which happens to be the default on other OSes, too. Actual lost requests are extremely rare, so there should be no practical downside to increasing the split timeout even on devices that work correctly. Signed-off-by:
