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These were originally made failable back in 2017 when if_initialize allocated a softint in every interface for link state changes, so that it could fail gracefully instead of panicking: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 And that softint in every interface has since been replaced by a single global workqueue, because link state changes require thread context but not low latency or high throughput: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.

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.

ozaki-r | branches: 1.12.2; Move bpf_mtap and if_ipackets++ on Rx of each driver to percpuq if_input
The benefits of the change are: - We can reduce codes - We can provide the same behavior between drivers - Where/When if_ipackets is counted up - Note that some drivers still update packet statistics in their own way (periodical update) - Moved bpf_mtap run in softint - This makes it easy to MP-ify bpf
Proposed on tech-kern and tech-net

if_schedule_deferred_start checks if the if_snd queue contains packets, so drivers don't need to check it by themselves.

ozaki-r | Introduce softint-based if_input
This change intends to run the whole network stack in softint context (or normal LWP), not hardware interrupt context. Note that the work is still incomplete by this change; to that end, we also have to softint-ify if_link_state_change (and bpf) which can still run in hardware interrupt.
This change softint-ifies at ifp->if_input that is called from each device driver (and ieee80211_input) to ensure Layer 2 runs in softint (e.g., ether_input and bridge_input). To this end, we provide a framework (called percpuq) that utlizes softint(9) and percpu ifqueues. With this patch, rxintr of most drivers just queues received packets and schedules a softint, and the softint dequeues packets and does rest packet processing.
To minimize changes to each driver, percpuq is allocated in struct ifnet for now and that is initialized by default (in if_attach). We probably have to move percpuq to softc of each driver, but it's future work. At this point, only wm(4) has percpuq in its softc as a reference implementation.
Additional information including performance numbers can be found in the thread at tech-kern@ and tech-net@: http://mail-index.netbsd.org/tech-kern/2016/01/14/msg019997.html
