iwn(4): (partially) rewrite A-MPDU Tx path 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).

The latter could cause stability issues. Tested: * Tested on Intel 6300, STA mode. Differential Revision: https://reviews.freebsd.org/D25113 bwi: clean up empty lines in .c and .h files mwl: clean up empty lines in .c and .h files Fix ieee80211_radiotap(9) usage in wireless drivers: - Alignment issues: * Add missing __packed attributes + padding across all drivers; in most places there was an assumption that padding will be always minimally suitable; in few places - e.g., in urtw(4) / rtwn(4) - padding was just missing. * Add __aligned(8) attribute for all Rx radiotap headers since they can contain 64-bit TSF timestamp; it cannot appear in Tx radiotap headers, so just drop the attribute here. Refresh ieee80211_radiotap(9) man page accordingly. - Since net80211 automatically updates channel frequency / flags in ieee80211_radiotap_chan_change() drop duplicate setup for these fields in drivers. Tested with Netgear WG111 v3 (urtw(4)), STA mode.

Haiku
Homepage | Mailing Lists | IRC Channels | Issue Tracker | API docs
Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.
Goals
- Sensible defaults with minimal configuration required.
- Clean, clear, concise code.
- Unified desktop environment.
Trying Haiku
Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.
Compiling Haiku
See ReadMe.Compiling.
Contributing
Haiku is a meritocratic open source project with a large variety of tasks. Even if you can't write code, you can still help! Haiku needs designers, (technical) writers, translators, testers... Get involved and help out!
Contributing code
If you're submitting a patch to us, please make sure you're following the patch submitting guidelines.

Contributing documentation
The main piece of documentation that still needs work are the API docs (found
in the tree at docs/user). Just find an undocumented class, write
documentation for it, and submit a patch.
