tristate "High-availability Seamless Redundancy (HSR)"
---help---
If you say Y here, then your Linux box will be able to act as a
DANH ("Doubly attached node implementing HSR"). For this to work,
your Linux box needs (at least) two physical Ethernet interfaces,
and it must be connected as a node in a ring network together with
other HSR capable nodes.
All Ethernet frames sent over the hsr device will be sent in both
directions on the ring (over both slave ports), giving a redundant,
instant fail-over network. Each HSR node in the ring acts like a
bridge for HSR frames, but filters frames that have been forwarded
earlier.
This code is a "best effort" to comply with the HSR standard as
described in IEC 62439-3:2010 (HSRv0) and IEC 62439-3:2012 (HSRv1),
but no compliancy tests have been made. Use iproute2 to select
the version you desire.
You need to perform any and all necessary tests yourself before
relying on this code in a safety critical system!
If unsure, say N.

On Ideapad laptops, ACPI event 1 is currently not handled. Many models
log "ideapad_laptop: Unknown event: 1" every 20 seconds or so while
running on battery power. Some convertible laptops receive this event
when switching in and out of tablet mode.
This adds and additional case for event 1 in ideapad_acpi_notify to call
ideapad_input_report(priv, vpc_bit), so that the event is reported to
userspace and we avoid unnecessary logging.
