riastradh | if_attach and if_initialize cannot fail, don't test return value
These were originally made failable back in 2017 when if_initialize
allocated a softint in every interface for link state changes, so
that it could fail gracefully instead of panicking:
https://mail-index.NetBSD.org/source-changes/2017/10/23/msg089053.html
However, this spawned many seldom- or never-tested error branches,
which are risky to have around. And that softint in every interface
has since been replaced by a single global workqueue, because link
state changes require thread context but not low latency or high
throughput:
https://mail-index.NetBSD.org/source-changes/2020/02/06/msg113759.html
So there is no longer any reason for if_initialize to fail. (The
subroutine if_stats_init can't fail because percpu_alloc can't fail
either.)
There is a snag: the softint_establish in if_percpuq_create could
fail, potentially leading to bad consequences later on trying to use
the softint. This change doesn't introduce any new bugs because of
the snag -- if_percpuq_attach was already broken. However, the snag
can be better addressed without spawning error branches, either by
using a single softint or making softints less scarce.
(Separate commit will change the signatures of if_attach and
if_initialize to return void, scheduled to ride whatever is the next
convenient kernel bump.)
Patch and testing on amd64 and evbmips64-eb by maya@; commit message
soliloquy, and compile-testing on evbppc/i386/earmv7hf, by me.

Implement the BPF direction filter (BIOC[GS]DIRECTION). It provides backward
compatibility with BIOC[GS]SEESENT ioctl. The userland interface is the same
as FreeBSD.
This change also fixes a bug that the direction is misunderstand on some
environment by passing the direction to bpf_mtap*() instead of checking
m->m_pkthdr.rcvif.

Stopgap for PR kern/47957: when reinitializing the chip in if_timeout,
avoid pmf operations as we are called from softint context.
This is not a 100% solution, since we still may end up panicing if
initialization fails.
Instead of hacking around it on a per driver level, wouldn't it be better
to have a single global workqueue and dispatch the if_slowtimo() calls
via that?

christos | This is the initial port of OpenBSD's athn(4) driver. It supports
quite a few Atheros 802.11n devices. See the athn(4) manpage for a
list.
This port has only been tested with a TP-LINK TL-WN722N USB adapter
which has an AR9271 chipset (VENDOR: 0x0cf3, PRODUCT: 0x9271). The
BSS, Monitor, and HostAP modes all seem to work on that adapter,
though the later has not been tested much.
The driver also supports PCI and CardBUS devices, but those interfaces
are completely untested and probably won't work at this point.
If someone can provide me with other adapters that should be
supported, particularly PCI or CardBUS adapters, or tell me where I
can get one cheaply, I would be happy to try to get the driver working
on those devices as well.

if_initalize() and if_attach() failed when resource allocation failed
(e.g. allocating softint). Without this change, it panics. It's bad because
resource shortage really occured when a lot of pseudo interface is created.
To avoid this problem, don't panic and change return value of if_initialize()
and if_attach() to int. Caller fanction will be recover from error cleanly by
checking the return value.
Return if bah_attach_subr() failed.
If if_attach() failed in the attach function, return.
- If if_initialize() failed in the attach function, free resources and return.
- Add some missing frees in bridge_clone_destroy().
- KNF
If error occured in bcmeth_ccb_attach(), free resources and return.
If error occured in pq3etsec_attach(), free resources and return.
If error occured in the attach function, free resources and return.
- If if_initialize() failed in athn_attach(), free resources and return.
- Add missing pmf_event_deregister() in athn_detach().
- Free resources correctly on some errors in atw_attach().
- Use apint*() insread of printf() in the attach function.
If if_initialize() failed in the attach function, return.
- If if_initialize() failed in the attach function, free resources and return.
- Add missing dwc_gmac_free_dma_rings() and mutex_destroy() when attach
