Increase the default allowed number of reconstruction attempts. There's not an exact right number for this setting. It needs to be set large enough to cover any realistic failure scenarios and small enough to avoid stalling the IO pipeline and invoking the dead man detection. The current value of 256 was empirically determined to be too low based on multi-day runs of ztest. The fault injection code would inject more damage than could be reconstructed given the relatively small number of attempts. However, in all observed cases the block could be reconstructed using a slightly higher limit. Based on local testing increasing the default value to 4096 was determined to strike the best balance. Checking all combinations takes less than 10s in the worst case, and has so far eliminated the vast majority of false positives detected by ztest. This delay is roughly on par with how long retries may be performed to a misbehaving HDD and was deemed to be reasonable. Better to err on the side of a brief delay rather than fail to reconstruct the data. Lastly, the -Y flag has been added to zdb to make it easy to try all possible combinations when performing split block reconstruction. For badly damaged blocks with 18 splits, they can be fully enumerated within a few minutes. This has been done to ensure permanent errors are never incorrectly reported when ztest verifies the pool with zdb.

This is CVS revision 1.31 from NetBSD lib/libedit/chartype.c: Make sure that argv is NULL terminated since functions like tty_stty rely on it to be so (Gerry Swinslow) This broke when the wide-character support was enabled in libedit. The conversion from multibyte to wide-character did not supply the apparently expected terminating NULL in the new argv array.

Add parentheses to perform assignment before comparison.

From NetBSD: Since the MAC can get stuck in reset state with no link, ignore reset timeouts and continue with initializing the device. Fixes "soft reset timeout" issue at boot with no network cable plugged in. awg_init may be called multiple times throughout normal interface usage, so the tx/rx descriptor base address registers must be written after each MAC reset and are moved as such. This problem has been observed on FreeBSD, H3/H2+ devices with an internal PHY (includes OrangePi R1, OrangePi One at least).

Generic Tx stats fixes: - do not try to parse "aggregation status" for single frames; send them to iwn_tx_done() instead; - try to attach mbuf / node reference pair to reported BA events; allows to fix reported status for ieee80211_tx_complete() and ifnet counters (previously all A-MPDU frames were counted as failed - see PR 210211); requires few more firmware bug workarounds; - preserve short / long retry counters for wlan_amrr(4) (disabled for now - causes significant performance degradation). - Add new IWN_DEBUG_AMPDU debug category. - Add one more check into iwn_tx_data() to prevent aggregation ring overflow. - Workaround 'seqno % 256' != 'current Tx slot' case (until D9195 is not in the tree). - Improve watchdog timer updates (previously watchdog check was omitted when at least one frame was transmitted). - Stop Tx when memory leak in currently used ring was detected (unlikely to happen). - Few other minor fixes. Was previously tested with: - Intel 6205, STA mode (Tx aggregation behaves much better now). - Intel 4965AGN, STA mode (still unstable).
