Merge WiFi net80211, drivers, and management in order to support better 11n and upcoming 11ac. This includes an ath(4) update, some run(4) 11n support, 11n for otus(4), A-MPDU, A-MSDU, A-MPDU+A-MSDU and Fast frames options, scanning fixes, enhanced PRIV checks for jails, restored parent device name printing, improvements for upcoming VHT support, lots of under-the-hood infrastructure improvements, new device ID, debug tools updates, some whitespace changes (to make future MFCs easier). This does not include (most) epoch(9) related changes as too much other infrastructure was not merged for that. Tested on: some ath(4) AP, run(4) STA, and rtwn(4) STA Discussed with: adrian (extremely briefly) Sponsored by: Rubicon Communications, LLC (d/b/a "Netgate") [partially] Approved by: re (gjb) Relnotes: yes

MFC r344990:

2019-03-28T09:16:00Z

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.

Reapply, with minor tweaks, r338025, from the original commit:

2018-09-26T17:12:14Z

Remove unused and easy to misuse PNP macro parameter Inspired by r338025, just remove the element size parameter to the MODULE_PNP_INFO macro entirely. The 'table' parameter is now required to have correct pointer (or array) type. Since all invocations of the macro already had this property and the emitted PNP data continues to include the element size, there is no functional change. Mostly done with the coccinelle 'spatch' tool: $ cat modpnpsize0.cocci @normaltables@ identifier b,c; expression a,d,e; declarer MODULE_PNP_INFO; @@ MODULE_PNP_INFO(a,b,c,d, -sizeof(d[0]), e); @singletons@ identifier b,c,d; expression a; declarer MODULE_PNP_INFO; @@ MODULE_PNP_INFO(a,b,c,&d, -sizeof(d), 1); $ rg -l MODULE_PNP_INFO -- sys | \ xargs spatch --in-place --sp-file modpnpsize0.cocci (Note that coccinelle invokes diff(1) via a PATH search and expects diff to tolerate the -B flag, which BSD diff does not. So I had to link gdiff into PATH as diff to use spatch.) Tinderbox'd (-DMAKE_JUST_KERNELS). Approved by: re (glen)

Back out r338035 until Warner is finished churning GSoC PNP patches

I was not aware Warner was making or planning to make forward progress in this area and have since been informed of that. It's easy to apply/reapply when churn dies down.
